- Getting the permits to sell food (in Chicago of all places)
- Getting a one day location
- Figuring out legal liability (who gets sued if somebody gets hurt/sick)?
- How are those custom design bags, wrappers, uniforms going to be produced? A McDonalds or Burger King supplier or 3rd party?
- How are you going to get workers for that one day for that one location? Do you have to hire temporary workers or do you divert existing workers? How will that impact overtime and other local labor laws (in Chicago)?
- How is the actual burger constructed? Do patties come from McDonalds or Burger King suppliers? What about the buns? What about everything else? Are side orders like fries and drinks going to be available.
- If McDonalds and Burger King cross-promote different specific brands like Coke or Pepsi or Heinz or Del Monte, who do they use?
I'd really like to know how this would work out.
