Stop in for a cup of coffee

Health inspector checked out the old party wagon today and said in order to sell hot dogs I have to have a refrigerator on the truck, ice chest is not going to work.
I passed everything but the fridge. SO think instead of buying a propane or electric fridge I'll just sell packaged food individually wrapped that doesn't need to be cold. Also canned beverages in an ice chest he said I would be able to do that.
