Nothing wrong with McDonald's in the states. The guy is probably some hippie who thinks he's too good for fast food. You know, the type who flairs his nostrils if he can't order his favorite bottle of wine at a restaurant.
(Not the author, just another McDonald's hater.) It's not an elitist thing at all. I think McDonald's is absolutely disgusting and no one should eat there, not that I'm above it. And I don't even drink wine.
