Not very PC
Gordstar; chronic over-eaters generally have woes which apply to smokers, alcoholics, druggies and other comfort-seeking escapists. Which, let's be honest, applies to all of us to some extent - certainly to me on a Friday night. But I sympathise with your take.
I'm reminded of a post on here a while back. Someone quoted a survey whereby 85% of compaining pax said they were miffed at the obesity of the person next to them. The other 15% complained that... the inflight food portions were too small. Can't say I buy it, but I liked the story.
