What should a server do if a guest has a food allergy?

When a guest informs a server about a food allergy, the most appropriate action is to inform the kitchen and double-check menu items. This is crucial for several reasons. Understanding the potential severity of food allergies, it's essential to ensure that there is no cross-contamination or inclusion of the allergenic ingredient in the dish being prepared. By keeping the kitchen informed, it allows chefs to take necessary precautions and possibly suggest alternative dishes that are safe for the guest.

Additionally, double-checking menu items helps to provide the guest with accurate information regarding what they can safely eat. This diligence not only ensures the safety and satisfaction of the guest but also protects the establishment from liability and helps maintain a reputation of care and attentiveness towards customers' needs.
