A queue data structure is the most appropriate to simulate waiting customers because it follows the FIFO (First-In-First-Out) principle, which is consistent with how customers would line up at a cashier. When a new customer enters the queue, they are added to the end of the queue, and when a cashier becomes available, the customer at the front of the queue is the next to be served. Adding an additional cashier would mean having two queues (one for each cashier) or alternately, managing a queue of customers that can be routed to one of two cashiers.
