If someone orders a "Coke", they should be given a Coke. Don't make the rest of us repeat ourselves because someone is stupid enough to order something other than they want.
Don't make me repeat myself. I have told more than one place I wouldn't be back because of it. And i have heard from one place it really shook things up to the point of doing something about it.
Don't put up with mediocrity. Don't be a pain in the butt either.
