A guy lost like $800,000 the same day in Vegas (He had already been clearly drunk and the Casinos still served him alcohol, so naturally he was playing stupid bets(High bets that wouldn't make sense to someone who wasn't really drunk) and he sued after getting sober claiming he shouldn't have been given even more alcohol after being clearly drunk. The Casinos countered with basically,"We are not his parents and he is not our child nor is he a child. We shouldn't have to tell a grown adult to stop drinking and gambling." IIRC, the Casino staff did mention they knew he would go after them so bad for his lost money when he sobered up and he did. He lost his lawsuit, making him a loser twice .
Should he have won his lawsuit? I mean in my job that sells alcoholic drinks, we are told not to sell someone who is already really drunk any liquor. Bars are supposed to cut off people who are really drunk too. I saw an article saying that the guy was stumbling, slurring his words and they were still serving him alcohol. On the other hand he is an adult and didn't have to get that drunk, so I don't know.
