I try to be kind, but I'll admit that it is a little annoying to sit beside an overweight person whose belly roll oozes into my seat when that person eats throughout the game. Is it that hard to sit through a game without eating? Some people may have health issues that require them to eat, but I'd guess that most don't.
If you're already too fat to fit into one seat, it may be good to go a few hours without eating. I'm thin without much in reserve and I can do it. It's not so hard.
