Too many variables to drop off and leave. I don't think the host understands what is involved with temp. issues, refill issues and the time and effort it takes to keep things warm during a long serving time. It looks easy but it is a lot of work and the host will have to decide to be a host or a server. Guess what he will do? Meet and greet, have a few adult beverages and low and behold, the food gets out of the safe holding temp. and people get sick. Guess who gets blamed?
