My previous job was to run married and family retreats in the northeastern United States for Army Reserve Soldiers and their families. We would contract with hotels for rooms and meeting space. My team and I would show up on Thursday and set up for Friday attendee arrivals and run a three day event. As we came to our first Hilton hotel, the events coordinator met with us and gave my NCO and I a symbol so that the hotel staff would recognize that we were the decision makers for the event. The symbol was a pineapple pin emblazoned with "HILTON" that we wore on our collars.
