It's a lot more common than you'd think, and people just mind their own business when they shouldn't. Some people have this attitude like women are responsible for whatever happens to them if they choose to get drunk. But sometimes they're not just drunk and they didn't voluntarily get that way because someone put something in their drink, or maybe they were taking medication that interfered with their alcohol absorption, or really whatever. (Not that it should even matter; people should be able to get drunk and it doesn't mean anyone is allowed to hurt them... I'm just saying that the circumstances could be more deadly than simply drinking too much.)

I hate that bouncers just throw people out on the street if they're too drunk or passed out and don't bother to call an ambulance or someone in their phone to come get them (depending on the circumstance). If bars are liable for underage people drinking then then should also be liable for negligently allowing people to be in a situation where they could get seriously hurt when they're in a position to at least attempt to intervene. It's like, the bouncers are standing outside anyway, surely they can keep an eye out and make sure someone gets a safe ride home. I think this especially applies to women but it should also apply to men.
