Final answer:
Servers package customers' leftovers typically at their discretion or based on the restaurant's policy. This is a common practice aimed at enhancing customer service and satisfaction.
Step-by-step explanation:
Whether servers package up customers' leftovers for them can vary from restaurant to restaurant. Typically, in most dining establishments, a server will offer to package leftovers for the customer. While the practices might differ slightly, it's quite common for servers to provide this service by transferring the food to a takeout container either at the table or in a designated area away from the dining space.
Customers can then take their leftover food home and enjoy it later. Some restaurants might have a policy where they instead provide customers with the container and allow them to pack their leftovers themselves, while others might have the server complete the task. This practice is seen as a part of customer service that ensures a pleasant experience and customer satisfaction.
