I always wonder what goes through their minds at the Chinese buffet.  There seems to be the worst of the worst there.  Fat people literally piling up short ribs and hovering over their dish as they eat, facing the buffet as if to keep tabs.  Then you see a busboy on his break, eating his lunch, a single plate of vegetables.  I imagine they're either indifferent, saddened or sadistically exploitive.  I can't imagine all the fat they see on a weekly basis and the horrible behavior.
