Why are fat people often hypocritically rude to skinny people?

I know what you mean. its MOST, not all. I know some very nice overweight people, who are really sweet. Its mostly the strangers on restarurant workers who are rude to me. I try to smile at them and say Good morning or whatnot, and they always seem to have that little attitude problem, and roll their eyes, or snatch my ATM from me. I try to be as polite as possible to them, but its when i get MY attitude that they calm their horses. I hate having to do that, why can't they be nice in the first place. DONT GET ME WRONG, I have met MANY skinny girls with Serious attitude problems, who think they are better than everyone. I guess people of all shapes and sizes have issues! Brighten up people, life is nice! Stop complaining about it.
