Admittedly, delight and satisfaction share common characteristics. According to the expectancy-disconfirmation model (Oliver, 1980), customers are expected to compare pre-purchase expectation with the actual experience of product or service. If perceived performance fails expectation, dissatisfaction or outrage will occur. If perceived service quality exceeds expectation, then positive responses such as satisfaction or delight will arouse. Therefore, delight and satisfaction are unified by their nature as positive emotions.
