Recently, [a vegan customer sued Burger King because a plant-based burger he bought at a Burger King franchise was cooked on a grill also used for cooking meat][1].

This got me thinking: who would usually be liable for this sort of case?

Would it be...

- the franchisor (Burger King),
- the franchisee (the actual restaurant owner), or
- the employee

I'm interested in not only the answer in Florida, where this occurred, but in other places around the world too.
