What is the final question a cashier should ask when handing a customer their order?

When interacting with a customer and preparing to hand over their order, it's essential for the cashier to ensure that the customer has everything they need to enjoy their meal. Asking if they would like any parmesan or plastic silverware directly addresses possible enhancements to their dining experience. This question demonstrates attentiveness to the customer's needs and preferences, which fosters a positive interaction.

Offering additional items, such as parmesan cheese for enhancing the flavor of the meal or the convenience of plastic silverware, shows that the cashier is not only focused on the transaction itself but is also considering the customer's satisfaction. This added layer of service can make a significant difference in how the customer perceives their overall experience and the establishment.

The other options, while relevant in different contexts, do not encapsulate this customer-centered service approach in the same way. For instance, offering a receipt is a standard procedure but does not enhance the customer's immediate dining experience. Similarly, asking about tips or help carrying the order pertains more to financial matters or logistical assistance rather than enhancing the meal itself, which is the focus of the final question.
