You recently hosted a wedding where a groomsman, who was allergic to nuts, ate a passed hors d'oeuvre (hazelnut crusted chicken skewers), went into anaphylactic shock, and had to be taken to the hospital. What is a policy and/or procedure that addresses either 1) what to do if this happens at another event (i.e., how to handle a medical emergency at an event) or 2) how to prevent this from happening in the future
