2. Literature Review
Service is an interactive activities between server and client by which the server tries to fulfil needs, expectations, and raise satisfaction and impression (Abraham and Taylor, 1999; Gronross, 1990). Services can be defined as deeds, efforts, or performance (Berry, 1980).
The literature of Parasuraman, Zeithaml and Berry (1985) mentions service-intangibility, variability, and inseparability that must be understood to study the service issues. Service includes unique features such as intangibility, inseparability and variability (Hoffman and Bateson, 2008). Intangibility is the state when service cannot be readily displayed. Inseparability implies that service is not separated from their providers, and it is not stored for the later use (Kotlar, Armstrong, Saunders and Veronica. 2002). Additionally, variability refers to the quality of service depending on the service provider as well as when, where and how service is provided
