Some researchers have proposed generic service quality models. It is believed that the
models can be used for measuring service quality of various services [18]. Parasuraman et al. [18]
proposed a generic model that is called as Servqual. Servqual reveals that service quality consists of

five dimensions, namely tangibles, reliability, assurance, empathy, and responsiveness [18].
Servqual is the service quality model that is widely adopted by service quality researchers [23],
including fast food restaurant service quality researchers [10]. However, Servqual has some
fundamental problems [23]. First, the model only includes service quality dimensions that can be
categorized as functional quality dimension [23]. In other hands, technical quality dimension is
excluded [23]. Second, the stability of Servqual’s dimensions is also questioned [23]. This is
because the number of Servqual’s dimension was changes when researchers retested the model [23]
