It is important to distinguish between service and goods. Goods are most tangible which can be refer as an object that the customer can see, touch or taste while services based on the business perspectives are more of a valuable action, a deed, performance or an effort to satisfy a need and fulfil the demand from the customer (Rouse,2012). There are many definitions of services in the literature may depend on the scholars and focus on a specific research (Groonros, 2001). However, one of the most important and unique characteristics of services is that services are processes, not things, which mean that a service firm has no product or does not produce a tangible commodity and only an interactive process. Groonros (2001) offer a comprehensive definition of services where services is "an activity or series of activities of a more or less intangible nature than normal, but not necessarily, take place in the interaction between the customer and the service employees and/or physical resources or goods and/or systems of the service provider, which are provided as solutions to customer problems".
