Final answer:
The perception of self-service taking too much time varies among customers, depending on factors such as the efficiency of the system and familiarity.
Step-by-step explanation:
The perception that self-service takes too much time can vary among customers. Some customers may find it convenient and time-saving to use self-service options, while others may feel that it takes longer compared to being served by a person. It ultimately depends on the efficiency of the self-service system and the familiarity of the customer with using such systems. For example, a customer who is experienced with self-checkout at a grocery store may find it quicker than waiting in a line with a cashier. On the other hand, a customer who is unfamiliar with the self-service kiosks at an airport may perceive it as time-consuming.
