by Cardozo (1965). Reisinger and Turner (2003), said that satisfaction is related to expectations and travel experience, with comparison of the experience and expectations, feeling of satisfaction, the customer is satisfied; the other hand, the resulting discontent, and vice versa. As for the possibility of revisiting, is relevant with overall customer satisfaction.
When performances are below expectations, the disconfirmation is negative, which means customers are dissatisfied; when performances equal to expectations, customers are satisfied; when performances outperform expectations, the disconfirmation is positive, and customers are particularly satisfied. Therefore, the influences of satisfaction primarily are cognitive performance, expectations, and disconfirmation, but other factors are still many.
PZB Service Quality Model
Among the relevant literature on discussion of service quality, scholars define service quality as results between customer expectations for service and comparison after service performance. Sasser et al. (1978) stated that the service standards and service quality is similar to the concept of customer service, which is the level and degree of internal and external benefits for customers, can be divided into expected service levels and cognitive service levels. Churchill and Suprenant (1982) proposed that service quality is the customer satisfaction with the services, depending on the differences between actual service and original expectations.
Parasuraman et al. (1985) proposed "service quality gap model (Gap model)", is widely adopted related service quality models , it is posited that the service quality is determined by gap between customer expectations beforehand and afterwards cognitive impact. The influential factors are external communication, personal needs, reputation and past experience and others. As for customer awareness after receiving the service, is affected by the service provider, impact of the service delivery process and marketing. Investigating managers and customers in credit cards, securities business, banking, product maintenance by using depth interviews, discovered the existence of a gap between customer expectations and actual experience of service, the study resulted in the famous "PZB service quality model", as shown in Figure 1.
