What's the Difference Between a Diner and a Franchise?

I just think you can't make many changes but possibly a couple I have noticed in franchises occasionally there are ever so slight differences. There's certain types of dish which they don't do in some franchises just because the owner of that franchise has decided it's too awkward or they don't want to do it rightYeah and sometimes I don't know I can't tell the difference for example if Starbucks is a franchise or a chain McDonald's or Burger King I really don't know if they're franchises or chains well that's the thing isn’t I think these days quite often there's a mixture.
