Abstract This study proposed to measure the level of loyalty of Muslim consumers in Kopitiam restaurants. As such, 250 questionnaires were administered to 250 of the consumers who visited the restaurant located in Klang Valley. The survey instrument measuring loyalty was adopted and adapted from past studies. The data was analyzed by using Rasch analysis. The findings revealed that generally, the level of loyalty towards Kopitiam was moderately high as indicated by the loyalty ruler whereby the majority of the respondents were at high logit of the ruler. Specifically, those who were found to be very loyal were those who perceived the halal logo as being true or original. The implications of the findings to owners of Kopitiam restaurants were provided.
Keywords: Halal certification logo, Kopitiam, restaurant loyalty, Muslim consumers, Absolute consumer experiential value
1.0 Introduction
The history of Kopitiam began with the migrants known as Hainan. In the
1850s, the Hainan people migrated to South East Asia. They were the latest
migrants compared to the Hokkiens and Teochews. As the Hokkiens and Teochews
have stabilized their living in the agriculture, commerce and trade sectors, the
Hainanese struggled to find jobs in the less profitable trade (Food Blog Malaysia,
2010). Most of them ended up working in the service sectors as the cook, waiter or
servant in local hotels, restaurants, bakeries and bar, and also an operator in military
bases as seamen and sailors. Soon the Hainanese progressed to involve
themselves in the Kopitiam business as stallholders and assistants (Food Blog
Malaysia, 2010).
Kopitiam is a very famous brand in the South East Asia countries such as
Malaysia, Singapore and Riau Islands (Cheng, 2010). Every Kopitiam restaurant has
its uniqueness or niche in terms of taste and personality. However, there are still
some similarities that are shared commonly with other Kopitiam owners. The
ambience of Kopitiam is very unique to the Malaysian culture due to a combination of
different cultures. Despite, there is still similarity among the restaurants in terms of
marble table, and chair with woody round back and marble on the seat. As of today,
Kopitiam has gained popularity among the Muslims especially with the appearance
of the halal logo. According to Robert (as cited in Rajagopal, Ramanan, Visvanathan,
and Satapathy (2011)), the Muslim population of today constitutes a quarter of the
world population. This trend is expected to increase by 30 per cent in 2025. This
means that the number of Muslims around the world is increasing and this also
MALAYSIAN JOURNAL OF CONSUMER AND FAMILY ECONOMICS

implies that the level of awareness towards "halal" will increase. Moreover,
according to Chaudry and Riaz (as cited in Blaim and Muatasim, 2012), the critical
concern of Muslim consumption decision is deeply into whether a product is halal
especially in food. Thus, halal regulation and certification are developed to facilitate
the consumers in identifying products that are Syari’ah compliant.
Additionally, according to Blaim and Muastasim (2012), the demand for more
transparency in product ingredients has also increased from Muslim consumers.
Muslim consumers do not simply trust a simple halal mark, especially when the
products are imported from non-Muslim countries. The sense behind halal
certification is in providing a trustworthy signal for Shari'ah compliant products. As of
currently, the mission for transparency in the certification market has not been
entirely fulfilled by traders (Blaim and Muastasim, 2012). When Blaim and
Muastasim (2012) claimed that Muslim consumers do not simply trust the simple
halal logo, would this perception affect their level of loyalty towards a store or
restaurant? Would Kopitiam's ambience having the Chinese image be chosen by
Muslims in Malaysia to dine with confidence? If there were quite a number of Muslim
consumers who chose to dine in Kopitiam, would they be loyal towards the store? If
they did, what were their reasons? As such, this study was conducted to provide
empirical evidence as to the level of loyalty among Muslim consumers based on their
perceptions of the halal certification logo displayed at Kopitiam restaurants.
2.0 Literature review
2.1 Store Loyalty
Many researchers in the area of marketing revealed that consumers are
generally satisfied and become loyal due to the location of the stores (Mafini and
Dhurup, 2015), nature and quality of the assortment of items in trade (Johannes C.
Bauer, Alexander J. Kotouc, Thomas Rudolph, 2012), pricing approach (Han and
Ryu, 2009), in-store promotions (Konuk, F.A, 2019), sales personnel (Kurian,
George and Muzumdar, Prathamesh M. (2017), physical attributes (Han and Hyun,
2017), store ambience (Jalil, NAA, Fikri, A, Zainuddin, A, 2016) and loyalty cards
(Magi, 2003). Nonetheless, Miranda et al. (2005) reported that from a review of a
number of store image studies, they concluded that they had not identified a link
between store attributes and store loyalty (Mitchell and Kiral, 1998). In fact, a study
conducted by Garton (1995) discovered that perceptions of quality and service
provided by a store contributed relatively little to the customer's intention to return to
the store. This is consistent with a study by Bloemer and De Ruyter (1998) in which
they discovered that there was no direct effect of store attributes on store loyalty.
However, in studies conducted by Zainuddin and Shariff (2015a) (2015b) (2015c),
they revealed that Muslim consumers preferred to visit retail stores that had been
certified as Halal by the relevant authorities. Similar findings were found where
Muslims as guests in hotels preferred to stay in Syari’ah compliant hotels every time
they travel (Zainuddin and Kamaruddin) (2015). Knowledge about the product has
also been found to play a role in crafting brand loyalty in a luxury restaurant (Pheng
and Chen, 2015).
2.2 Halal Certification Logo
The term halal certification logo was defined differently by scholars due to the
MALAYSIAN JOURNAL OF CONSUMER AND FAMILY ECONOMICS
68
different aspects that they observe. For example, Rajagopal, Ramanan, Satapathy
and Visvanathan (2011) found that the halal sign; certified logo; stamp of ministry;
and stamp of 9 municipalities were the aspects used to be known with the halal
certification logo. On the other hand, Ballantine, Hall, and Sharifah Zanneirah (2011)
defined the halal certification logo by looking at the aspects of religious practices,
knowledge and sensitivity of the restaurant owners. This is quite similar to the
definition provided by Mohd Yusoff (as cited in Ballantine et al., 2011). He defined
halal certification as a qualification test involved in food practices; wholly defining it to
include preparation, slaughtering, cleaning, processing, handling, disinfecting,
storing, transportation and management practices. From the above definitions, we
can regard halal certification logo as an entitlement to declare a restaurant as being
a halal outlet if, in all its operations of the food being, Syari’ah compliance is being
observed by the owner. This includes the certified logo, stamp of ministry and stamp
of 9 municipalities. Thus, the scope of halal certification involves the whole food
supply chain that complies with Islamic dietary rules, meaning not containing haram
materials.
Abdul, Ismail and Johari (2009) claimed that halal certification is important for
Muslim consumers as it is the only benchmark that indicates a product has fulfilled
its halal requirement. In addition, Blaim and Muastasim (2012) believed that halal
certification is a signal of trustworthiness in terms of the product's compliance with
the Syari’ah. On the supply side, Sharifah Zannierah, Hall and Ballantine (2012) also
found that restaurant owners perceived that halal certification indicates that the
respective restaurant has knowledge of permissible food, sensitivity and religious
practices of the Muslims.
Among the recent studies conducted on halal certification logo were those of
Ballantine et al. (2011) and Abdul, Ismail and Johahri (2009). Ballantine et al. (2011)
found that halal certification attributes generate trust and also portray food hygiene
and safety. Abdul et al. (2009) found that people of different ethnicity and religious
backgrounds have different perceptions of the halal certification logo. In Kuwait, for
example, Muslim consumers perceived the halal certification coming from Saudi
Arabia and Kuwait as being more favourable and trustworthy compared to those
products with halal certification originating from Malaysia, Indonesia and the
Philippines (Rios, 2014). Muslims are mostly concerned with the logo as it is a
requirement of their religion and they do not presume that products produced by
Muslim countries are halal by default (Alsehan, 2010). Many believe that halal
certification is very prevalent in the hospitality industry. As such, this promotes the
importance of restaurant owners to acquire knowledge of Muslim dietary restrictions,
sensitivity and religious practices. In other words, they should acknowledge that
halal certification signifies that it has some attributes that make it unique in terms of
conforming to Islamic dietary rules.
2.3 Absolute Consumer Experiential Value
Previous studies observed that consumers are now seeking value, choice and
great customer experience while they shop. Recent retailing literature indicates the
critical role of consumer experiential value as one which includes the creation of a
theatrical retailing environment, stress fun, excitement, and entertainment as well as
encouraging greater customer participation in the retail service experience (Baron et
MALAYSIAN JOURNAL OF CONSUMER AND FAMILY ECONOMICS
69
al., 2000; Mathwick et al., 2001).
Market trends also show the role of customer experiential value in attracting
growing concern among practitioners in the retail industry.
Next, Holbrook (1994) expanded the traditional conceptualization of
experiential value to incorporate three spheres – extrinsic versus intrinsic value,
active versus reactive value, and self‐ versus other‐oriented value. In a shopping or
retail context, extrinsic value is acquired by means of satisfying the utilitarian
consumption goals (such as saving money) (Babin et al., 1994); and return on
investment and service excellence (Amjad, Shamin and Abu Bakar Sedek, 2015).
On the other hand, intrinsic value is derived from an enjoyable and playful shopping
trip and other emotional experiences (Babin et al., 1994, Bagdare and Jain, 2013,
Ching and Hui, 2009). Meanwhile, reactive value refers to a situation in which
customers appreciate the physical shopping environment or respond positively to the
service personnel. Active value, in contrast, results from customers' efficient
manipulation of shopping resources to satisfy their functional or affective needs (Kim,
2002). The results of empirical studies, however, revealed that personal interaction
positively influenced the perceptions of efficiency and excellent value; physical
environment positively influenced the perceptions of playfulness and aesthetics; and
lastly all dimensions of customer experiential value (i.e. efficiency, return on
investment, service excellence, playfulness, emotional experiences and aesthetics)
positively influenced customer behavioural intentions.
2.4 Absolute Consumer Experience
There are a few good definitions of the consumer experience. For instance, in
Sundbo and Hagedorn-Rasmussens' (as cited in Walter, Edvardson and Öström,
2010) they defined consumer experience as "a mental journey that leaves a
consumer with memories of having performed something special, having learned
something or just for the fun of it". Additionally, Johnston and Clarks (2005)
described service as consisting of a consumer's service experience that is combined
with the consumer's perception of the service experience. Johnston and Clarks
(2005) extended the definition of service experience by means of relating the
experience with the service process, the organization, the facilities, other consumers
and how the service firm's representatives treat the consumers. Finally, Walter et al.
(2010) defined consumer experience as the direct or indirect process experienced by
the consumer based on the service process, the organization, the facilities and how
he or she communicates with the service and other consumers. In summing the
above, we can say that consumer experience is the aggregate experiences that have
occurred throughout a consumer's involvement with the supplier of service during the
service transaction (Meyer and Schwager, 2007).
Based on the above definitions, the absolute consumer experience can be
simply defined as the direct and indirect process experience that a consumer
underwent during visiting a place. Those process experience can be in terms of
performing something special, learning something or maybe just for having fun with
the service process; the organization; the facilities; and how the consumer
communicates with the service and other consumers.

There are very limited studies conducted on consumer perception of
restaurant outlets. From the years 2007 up to 2013, there were only three studies
conducted. Among them are attributes of food outlet chosen by U.S consumers (Liu
and Jang, 2009), factors influencing consumer perception of fast food (Goyal and
Singh, 2007), and lastly factors influencing consumer perception and satisfaction of a
restaurant (Kisang, Hye-Rin and Kim, 2012). Liu and Jang (2009) suggested that
there are five most important attributes that consumers in the U.S chose Chinese
restaurant as their food outlet. These included taste, food safety, food freshness,
environmental cleanliness and appropriate food temperature. Meanwhile, Goyal and
Singh (2007) found that taste, quality (nutritional values), ambience and hygiene
were factors that mostly influence consumer perception of fast food. Next, Kisang et
al. (2012) found that food quality is of major significance for a restaurant image,
behavioural intention and consumer satisfaction.
3.0 Research Methods
The ruler is produced by using Rasch measurement analysis and it uses logit
as its unit scale. 250 questionnaires were administered to 250 consumers who
frequently visited Kopitiam restaurants located in the Klang Valley. The survey
instrument used to measure store loyalty was adopted and adapted from past
studies. In the literature, the factors hypothesized to influence restaurant loyalty are
the perception of halal certification displayed at the store; absolute consumer
experience; and absolute consumer experiential value. The data from the
questionnaire were analyzed using the Rasch measurement model. Rasch analysis
was employed as it incorporates a method for ordering persons according to their
ability and ordering items according to their difficulty (Bond & Fox, 2015). The final
output of Rasch is a ruler that measures a person's ability (in this case his or her
loyalty). The goodness fit of the data was first determined before the final output of
Rasch (a ruler of restaurant loyalty) was produced. The findings revealed that
generally, the level of loyalty for Kopitiam is moderate as its mean score was 0.66
logit, which was slightly higher than the mean score of the item which was 0 logit.
This indicates that the higher the location of a consumer on the ruler against the 0
logit unit, the higher is the level of loyalty of the consumer towards the Kopitiam
restaurant. With reference to Figure 1, 55 per cent of the respondents were located
on the higher logit of the ruler (means High Loyalty).
4.0 Analysis and Results
4.1 The Determination of Goodness Fit of Data
Before the analysis was conducted to answer the research objectives, the
goodness of fit of data was first conducted to ensure the data fitted the Rasch model.
This involved several tests, namely consistency of response category test; overall
reliability of the items and persons; misfit items and persons; and the
unidimensionality of survey instrument used to measure the loyalty of -consumer.
4.1.1 Consistency of Response Category
The rating scale used for this study was the 5 point Likert scales of
agreement. The reason for this analysis to be conducted was to identify if the 5 point
MALAYSIAN JOURNAL OF CONSUMER AND FAMILY ECONOMICS
71
Likert scales were discriminated nicely by the respondents, indicating various levels
of ability through various responses on similar items. For example, a good item
would be able to receive different responses from different levels of ability (in this
study, ability refers to loyalty).
With reference to Table 4.1, there was very good discrimination of scale by
the respondents. This was indicated by the consistent increase in the value of the
observed average, the outfit MNSG which were less than 2, and most importantly the
differences between the category measures were in the ranges of +/-1.4. This
discrimination of the scales is illustrated in Figure 4.1. The gap between each scale
was clearly seen and this indicated good discrimination.
4.1.2 Fit Statistics
Table 4.2 shows the overall fit of the data for Rasch. In general, the mean
score for loyalty was low because the persons’ mean was located slightly above the
mean score of the items. This indicates the level of loyalty of Kopitiam consumers, in
general. Overall, the person reliability of .90 indicates that there were sufficient good
items to measure persons’ ability (loyalty level). The item reliability of .96 indicates
that there were sufficient true respondents to measure items difficulty level. The
Cronbach’s alpha of .92 was excellent indicating good internal item consistency in
measuring a variable.
4.1.3 Misfit Items and Persons
Misfit items and persons are very important to be determined because they
are also considered as outliers. The presence of misfits/outliers may affect the
accuracy of the findings. In Rasch, the misfits/outliers are not only referring to
persons, but also items. The misfit items are known as items that were understood
wrongly by many respondents and did not get the response as expected. These
items can either be removed or rephrased depending on the number of items
measuring the variable or it may also reflect different latent trait that a researcher
should acknowledge as unique or conflicting response from the respondents.
In order to know the items or persons as a misfit, there are three (3) important
indicators:
The mean square (MNSQ) which must be between the range of .5 to 1.5
The Z standard (ZSTD) which must be between the range of +/- 2
The point measure correlation (pt.mea.corr) which must be between .4 and
.83
If the measure for each item or person has the value of all the indicators
within the range, then the item and person are good that can be considered for the
next level of analysis. If all the three indicators are beyond the range specified, the
items should be removed or modified depending on the degree of importance.
With reference to Table 4.3, items SL3, SL2, HCL4, ACE2 and ACREV5 had
ZSTD score of higher than the required range of +/-2. However, as the other two
indicators (MNSQ and pt.mea.corr) were within the range, these items were
accepted.

4.1.4 Unidimensionality
Unidimensionality is to test the unidimensional characteristics of the survey
instrument used to measure loyalty. If the variance explained by the measure had a
value below 40 per cent of variance explained by the measure, then the survey
instrument is measuring other than one latent trait. Based on Table 4.4, the variance
explained by the measure was 42.8 per cent. This indicated that the survey
instrument measured what it was intended to measure. The eigenvalue of the first
contrast of 3.2 indicated excellent measures, fulfilling the required condition for
unidimensionality. Thus, this has confirmed the unidimensionality of the survey
instrument in terms of the loyalty of Muslims towards a Kopitiam restaurant. For this
analysis, Rasch had used the PCA.
Since the results for all types of tests conducted in the first analysis were
good, the second analysis was conducted to answer the objectives of the study.
4.2 Second Phase of Analysis: Rasch Ruler - A Ruler of Consumer Loyalty for Kopitiam Restaurant
With the analysis of the goodness of fit of data, it was concluded that the
items used to measure the variable ‘loyalty' were good. This also means that the
items were measuring what they intended to measure.
The second analysis was conducted to answer the research objectives, which
was to identify the level of store loyalty of Kopitiam consumers, especially Muslim
consumers. For this purpose, a person's item map was produced. The person's item
map was called a ruler of store loyalty, and this can be seen in Figure 4.2. This item
person's map was called ruler because it was able to measure the level of loyalty of
each consumer based on his or her perception of the originality of the halal
certification logo, his or her experience, and his or her value for the experience he or
she had in the store. The ruler divides the persons (or respondents) on the left side
as indicated by #, and divides the items as represented by HCL (Halal Certification
Logo), ACE (Absolute Consumer Experience), ACREV (Absolute Consumer
Experiential Value), and SL (Store/restaurant Loyalty). Persons and items were
arranged side by side of the ruler so that the ability (loyalty) of a person can be seen
from his or her ability to respond to sets of items. Each set of items (arranged by
column) was measuring each variable in the box. For instance, HCL1-HCL5
measured the Halal certification logo. The arrangement of the item was dependent
on the difficulty of the items.
With reference to Figure 4.2, the consumers were divided by 3 lines (identified
by Rasch Analysis, indicated by person separation of 2.93 (rounded to 3) as shown
in Table 4.2a in the appendix). The lines have divided the groups into 4 (high loyalty,
Loyal, moderate loyalty, non-loyal). Those with high loyalty (55 per cent of them)
responded positively to halal logo items, reflecting their confidence in the halal logo
displayed by the Kopitiam restaurant, which resulted in positive emotions and
feelings (indicated by items ACEs and ACREVs). These caused them to be loyal
(indicated by items SLs). Loyal consumers with above moderate level (or 22 per
cent) responded positively to some items of the halal logo (HCL1, HCL5 and HCL4)
which had caused them to agree only for items ACE4, ACE1, ACE5, ACE3 and
ACE2 of absolute consumer experience, ACREV2, ACREV6, ACREV1, ACREV5,
ACREV4 and ACREV3. This led them to agree with all the items of loyalty (SL1-
MALAYSIAN JOURNAL OF CONSUMER AND FAMILY ECONOMICS
73
SL4). The difference between respondent with high loyalty and above moderate level
loyalty was the agreement for items HCL3 and HCL2, ACE6 and ACE7, which might
result in a higher degree of agreement on all loyalty items. This is because the
higher the location of persons against items, the higher the agreement level for the
items. This explains why the other two groups of consumers were identified as being
less loyal. Noticed that most items of the halal logo (HCLs), Absolute Consumer
experience (ACEs) and Absolute Consumer Experiential Values (ACREVs) were
located above two groups (i.e., moderate loyal & non-loyal consumers).
Figure 1 : Person items map of restaurant loyalty from Rasch Analysis
With reference to Figure 4.2, those who were found to be very loyal are those
who perceived the halal logo as being true or original. This should lead them to
experience more positively in the store which later would lead to valuing what they
experienced in the restaurant. Those with the perception that the logo was not
genuinely halal, would not have a positive experience in the store, thus would fail to
value what the restaurant offers.
Specifically, the ruler indicated the important elements (or items) that have
caused consumers to increase the level of restaurant loyalty. For instance, item
HCL3 (checking for halal logo before entering Kopitiam restaurant) and HCL2 (halal
logo is strong evidence of halal food served in Kopitiam restaurant) are important
items that cause consumers to experience positive feelings with the restaurant’s
cleanliness and the appearance of waiters which are indicated by items ACE6 (feel
good to dine in Kopitiam because of its cleanliness) and ACE7 (enjoyed eating due
to the appearance of the waiters). HCL1 (believing that halal logo displayed at
Kopitiam reflect hygienic procedure) and HCL5 (confidence with halal logo displayed
at Kopitiam) are important items that cause consumers to experience good service
from waiters (ACE4), varieties of food choice (ACE5), enjoying the ambiance to stay
longer (ACREV2), value the moment with family and friends (ACREV6), and
admiring the setting up of the restaurant (ACREV1). This also means that HCL3,
HCL2, HCL1 and HCL5 are important reasons for consumers to be loyal because
they can experience good food and services only after they enter and enjoy the food.
The problem, however, is that they would only enter a restaurant after they check
and are confident with the halal logo displayed at the restaurant. Therefore, owners
of Kopitiam restaurants have to make sure that the halal logo is not fake and is
MALAYSIAN JOURNAL OF CONSUMER AND FAMILY ECONOMICS
74
updated each year.
In general, Muslim consumers have quite a positive perception of the halal
certification logo displayed at Kopitiam. This, in turn, leads to store loyalty due to
their confidence in enjoying the time spent in the restaurant. Their loyalty increases
when their perception of the logo increases. What follows is that their level of
experience with the food and restaurant also increases. This can be seen from the
item measure of each item against the location of each person displayed on the
ruler.
5.0 Discussion and Implications
The findings of this study have major implications on theory development and
practice. There was a lack of past research on store loyalty among Muslim
consumers in the aspect of their level of confidence with the originality of the halal
certification logo. A ruler measuring the loyalty of Muslim consumers that was
produced is new to the field as this highlighted the importance of the halal
certification logo. This is because with the right perception of the halal certification
logo, only then would consumers become loyal to the store as they had enjoyed the
time spent with their friends due to their confidence.
The novelty of this ruler can be seen from the creation of the ruler by using
the logit unit. An increase in a logit unit on the ruler would reflect an increase in
loyalty by one logit. What is interesting is that an increase in a logit unit means an
increase in perception with regards to the originality of the halal logo. When this
happens, this leads to an increase in the level of consumer confidence to experience
more with the food by a logit. This also means an increase in sales because loyalty
can be turned into increment in sales (Kasahun et al., 2012).
From the consumer's perspective, the findings of this study have supported
Abdul et al. (2009), Muatasim and Blaim, (2012), and Ballantine et al. (2011) as they
believe that the halal certification logo is very important to Muslim consumers to dine
or consume with confidence. This study also supported Zainuddin et al. (2015) who
explained that Muslim consumers prefer to visit restaurants with certified logo from
the relevant authorities. Those who perceived the logo as fake would never visit the
store the second time. Unfortunately, previous studies on store loyalty provided only
the mean score of store loyalty; thus there was no clear guideline on which important
aspects of consumer experience and consumer experiential value that have resulted
in the different levels of store loyalty among consumers. With the Rasch Ruler, a
clear gap can be seen between those with a high level of loyalty and those with no
loyalty. Thus, improvement or enhancement can be done if the owner wants
consumers to be loyal to his or her restaurant.
The present study has provided a scale of loyalty for Kopitiam owners to
enable them to identify items (elements) that improve loyalty among consumers.
Thus, Kopitiam owners can benefit from this study. The study has provided insights
to them in terms of crucial factors to increase store loyalty among Muslim
consumers. The owners should intensify their efforts by way of seeking, highlighting
and communicating the originality of their halal logo to their existing and prospective
consumers. These efforts will obviously improve the perception of the consumers on
the originality of the logo. Consequently, consumers can really enjoy the food and
the time they spend in the restaurant as they are confident with the religiosity
MALAYSIAN JOURNAL OF CONSUMER AND FAMILY ECONOMICS
75
element of the restaurant. Eventually, this will lead them to become loyal consumers
of the restaurant. One of the ways that Kopitiam owners can improve the perception
is by disclosing the consistent evaluation of the store with regards to the halal
certification that the owners have intensively worked upon to correct. This can be
done by displaying the compilation of the halal certification logo they receive each
year and possibly frame them accordingly.
6.0 Conclusion
The objective of identifying the level of store loyalty of Muslim consumers
towards Kopitiam restaurants located in Klang Valley has been achieved. 250
questionnaires were administered to Kopitiam consumers who visited the outlets.
The data were analyzed using the Rasch measurement model. A ruler of loyalty in
Rasch logit unit was produced. In general, Muslim consumers have confidence in the
halal certification logo displayed at the Kopitiam restaurant resulting in them
choosing it as a place to dine. Their loyalty for the restaurant was due to their
trustworthiness of the halal certification logo displayed in the restaurant. Their level
of loyalty, in general, was moderately high. The right perception has influenced them
to value their experience in the store resulting in them having quality time in the
restaurant. In other words, they are satisfied and enjoy the food as they are
confident with the food preparation. This will obviously enjoy the ambience of the
restaurant. This means that if a Kopitiam restaurant increases the level of
trustworthiness with reference to the logo, many Muslim consumers would have a
positive experience with the food provided, the waiters, the ambience and the time
spent in the outlet. As such, Kopitiam owners should focus on efforts that can further
convince their consumers with regards to the originality of their halal logo.
