Sale of food and drinks? I am not covering the cost of anything, you bring your parts, throw them on the floor, and people will buy them. I have run car shows and swap meets for decades and know how to manage them. I own the building and basically having an open house while providing a venue to buy and sell. Since I am not officially open for business I can't legally charge for anything. The only costs I will have it toilet paper, soap, and water for the bathrooms and I might even turn on the lights!
