Anyway, I think that you´re less likely to get rotten stuff at McD than in most other restaurants. My Mom is cook, so I know what´s going on.
Mc Junk is as steril as food gets. Everything they sell is deep frozen and then fried. No bacteria survive this.
Still, every time I see a McD I think of "Supersize Me" and the appetite is gone. That film is the mother of PR desasters! :D
