In accordance with SEM analysis result, for Thai consumer model, service marketing mix had both
direct and indirect influence on customer loyalty with the highest influence by physical environment
and process. In addition, service marketing mix also had high direct effect on perceived service quality
which responsiveness and tangibility are most important dimension to generate more loyalty. Although
internal marketing had no direct effect on customer loyalty, internal marketing still had indirect effect
on customer loyalty through perceived service quality. Additionally, the perceived service quality had
strong direct influence on customer loyalty which means customers certainly perceived good service
from 5 dimensions of perceived service quality. Therefore H1a, H1b, H2b and H3 are supported.
Since local consumers are more comfortable in terms of their transportation, place and time
were least important for them. In terms of internal marketing, it can be implied that most of halal
restaurants were small and owned by local Muslims, local consumers feel more relax when they use
the service; formal manner might not be much significant. Therefore; internal marketing has no direct
influence on customer loyalty in this model.
