Do I smell a new business?
Caliber industrial kitchen supply!
No, was a former pro wrestler and promoter. Concessions is really where the money is made and most venue have very little space so you have to improvise. Fastest money cow was pizza by the slice, popcorn, hot dogs, candy and can drinks. Fast, easy, cheap, and quick. One Turbo Oven can cook 3 whole pizzas in 4 minutes, Hot dogs can be roasted in the over, placed in bun, and foil wrapped under a heating lamp, popcorn can be popped from a machine, and the rest is pre-packaged.
Get the fuckers in, get their grub, and get them seating. Clean-up isn't bad
