When I used to travel, long haul, about twice or 3 times a month on business, I tended to keep to myself, eat and drink modestly, and sleep as much as I could.
However, on one trip years ago (on some horrible Combi-sort of plane) I sat next to a guy from Pakistan and we got chatting and drinking. And drinking. And drinking. I have no idea why, it just turned out that way.
The steward/stewardesses decided that we were perfectly OK, and decided to fuel us well before we asked. Looking back, I suspect that they must have had bets on about how much we could consume, and/or which of would collapse first. Eventually I must have slept/fallen in to a stupor.
Maybe Tightslot's rules would have saved me from the resulting brain damaging hangover.
