. Heterogeneity basically refers to the way in which a perception of quality can vary from one guest to the next, depending on his/her unique preferences and perceptions. The behaviour of the service provider influences the guest‟s perception of quality. Also bear in mind that the priority and expectations of the guest may alter, not only during the service deliver, but each time a service is used. In this regard it is also very difficult to reproduce a consistent service exactly the same way. Generally, when service as a whole is of good quality, the majority of the guests will share this perception, although their perceptions may vary slightly. Hotel managers must therefore have well-qualified and trained employees who are able to understand the requirements of a guest and are able to react in an appropriate manner.
