What is one of the questions you should ask every guest?

Asking about allergies and aversions is crucial for ensuring the safety and satisfaction of guests. This question allows staff to identify any dietary restrictions a guest may have, which is essential in preventing allergic reactions and ensuring that the meal meets the guest's preferences. It demonstrates a level of care and attentiveness to individual needs, fostering a welcoming dining experience.

While the other options can enhance the service provided, they do not directly address potential health issues or dietary restrictions. Knowing about allergies and aversions helps to create a more personalized and safe dining experience, making it the most essential question to ask every guest.
