Customer satisfaction has been a popular topic in marketing practice and academic research since
Cardozo's (1965) initial study of customer effort, expectations and satisfaction. Despite many attempts to
measure and explain customer satisfaction, there still does not appear to be a consensus regarding its definition
(Giese and Cote, 2000). Customer satisfaction is typically defined as a post consumption evaluative judgement
concerning a specific product or service (Gundersen, Heide and Olsson, 1996). It is the result of an evaluative
process that contrasts prepurchase expectations with perceptions of performance during and after the
consumption experience (Oliver, 1980)
