The worst passenger behaviour I ever saw was on a red-eye flight.
I had been bumped up to first class (score!) so I was all spread out in my fancy pants seat. There was no one next to me, and the cabin was pretty sparse in general. I figured it would be a drowsy, uneventful trip.
Mostly everyone else in first class quietly fell asleep. The only people who stayed awake were a younger guy a few rows forward and myself. I was half-watching Clint Eastwood’s Gran Torino, and he was getting drunk by himself. (Booze is free in first class on this particular airline.)
After he’d pounded back a couple cocktails and the better part of a bottle of wine, the flight attendant very politely suggested that he may have drunk his fill.
The guy exploded. “I paid $1,500 f***ing dollars for this!” (I don’t think that’s accurate.) “I’ll tell you when I’m f***ing done.” (That’s not how it works.) “Do you know who the f*** I am?” (I sure didn’t!)
The flight attendant, to her credit, did a very good job of remaining calm but firm. What really stopped the drinker dead, though, was when one of the older business guys in the row behind him woke up and chewed him out for being such an idiot.
After that, the drinker grumpily put his headphones in and didn’t say a word for the rest of the flight. When we landed in the morning, there were a couple of air marshals waiting in the terminal for our thirsty friend. I’m sure he got a nice talking-to to go along with his hangover.
Don’t be a jerk to your flight attendants. They don’t make airline policy, and 99% of them are just trying to ensure you get where you’re going safely and comfortably.
