RE: Consession Sales
I have been handling concessions for our club for 14 years. We are fortunate in that our clubhouse has a window facing the spectator area and a window facing the pit area so serving through both makes it nice. Not sure about the laws up your way but being a "non profit" normally does not mean you don't need licenses, inspections, etc (any revenue source to a local government is fair game). However, the reality may be that if you don't do this on a regular basis (weekly, etc) no one will give a hoot. We are located on private property (we own it) in the country and have never had any problems. We have also advertised events and always included "concessions available" without any problems.
I recently attended a local event at a club that is located at a public park facility and they had two vendors and I noticed that each had a local license. Might be a tad trickier to do your own stuff if you are on public land (parks, etc).
Not sure worse case here but we always figured if "they" said anything to us it would just be to not do it anymore unless we get whatever they think we need. We would address it then.
