Well I, being a hot chick, do not normally eat at fast food restaurants. I have eaten at Wendy's and Arby's on a very rare occasion and usually get a salad.
I work at mcdonalds. Yes they do. They are the same as all other people. It depends on the person, but I've seen them order pretty much everything on the menu. But I'm sure the individual person has their favorites.
By hot do u mean super skinny ano models or just attractive girls? Because fast food in any diet ( moderation) is acceptable and will not effect the person figure unless confused in mass and a healthy amount of exercise is evident.
