Do food courts with multiple restaurants share food? e.g. is there a common shipping and storage area?
Can you imagine McDonald's sharing space with Burger King, or KFC?

I wouldn't even be sure they'd be allowed to even if they wanted. Each establishment would need its own compliance &amp; hygiene certificate, which would be confounded if they shared space. Whose responsibility is each shared fridge in such circumstances? Who handles correct stock rotation? What happens if a KFC employee accidentally takes a bag of McDonald's fries?
