Final answer:
Apologize to the guest and try to accommodate their preference for a booth by indicating the wait time and ensuring their comfort during the wait.
Step-by-step explanation:
If a guest prefers a booth but none are available, the most appropriate course of action would be B. Apologize and try to accommodate their request if possible. This response shows a commitment to customer service and a desire to make the guest feel valued and respected. Offering a discount or ignoring their request are not ideal first responses and telling them they must wait without any courtesy may cause frustration.
Firstly, you should genuinely apologize for the inconvenience. Then explain the situation clearly, letting them know how long the wait might be for a booth to become available. If they are willing to wait, ensure they are comfortable and perhaps offer a complimentary beverage or appetizer while they wait, if it aligns with your business policies.
