I'm quite a bit shorter than average and frequently experience a world that doesn't quite fit me, such as pants and skirts I need to hem, head rests that my head doesn't reach, restaurant tables too high, etc. But I don't go around whining and demanding that everything be made to fit ME rather than the average person. And I can't even make different choices to be taller. So no, I won't pay more for airfare so that a 400 pound person can fit in the seat. Put down the cheeseburger, Deborah.
