My daughter use to work for McDonald's when she was in high school. I can still remember her telling me about the people that came in and ordered a hamburger/cheeseburger. LOL She would explain it was just written like that...you had to make a decision. I've noticed in the last year or more when I order a hamburger I will be asked if I want cheese on it..DUH...am I missing something here? Wouldn't that make it a cheeseburger????
