I had some teenagers playing Slap Jack on the table behind me one flight (you know, the game where you're required to quickly slap the pile of cards multiple times per game?). I let them play a few games, thinking they'd get a clue that maybe it's not great to play on a table attached to someone's seat, but they did not. So I turned around and told them to knock it off. Then politely suggested they play a game that didn't require slapping. Deer in headlights back at me, but they put the cards away
