Most of the times that I've been to car dealerships, I don't really notice the cashiers until it's time to pay. The dealership I went to recently to get an oil change, however, had a cashier right in the waiting room (which was also the location of the service and parts desk). Efficient placement that should probably lead to employees working hard, since they are in front of each other and customers. For this particular cashier, however, it was 90% texting in her chair along with 10% taking payments/other work, and it's a missed marketing opportunity.
