Answer:
c.
minimizing the amount of time customers wait is a key factor in service quality
Explanation:
The correct option is c. because most research on the subject has concluded that, mainly in Western society, customers that have to wait for service for too long of a time will most likely have a low satisfaction overall service quality, so minimizing the time customers wait is a key factor in service quality.
Option a. is incorrect because services should be adapted to different geographic regions based on their customers' characteristics, such as their response to waiting for service.
Option b is incorrect because even though shopper analytics can improve the wait time problem, they are not a key element for this example.
Option d. is wrong because, even if they receive the desired service, waiting is most likely not going to be considered acceptable to customers.
