Check this video, where a couple of young women are walking down a sidewalk late at night in what appears to be an entertainment district. They pass a staggering drunk who spits on one of them. They walk off screen, but then come back and one gets all up in his face, gesturing animatedly and obviously yelling. He flattens her because, yes, boys do hit girls.
Some staggering drunk gobs a lunger on me, I'm probably calling the heat. I'll stick around at a respectable distance and watch and see if he wants to spit on Johnny Law, too, because that's usually pretty entertaining. "Tase him again! Tase him again! Hit him with your OC!"
I'm not tangling with him though, because not even in Texas is "He spit on me, so I shot him full of holes" going to look good in court.
Protip: Nothing good happens after ten PM. Well, actually, lots of fun stuff does, but that's also when a lot of bad stuff does, too. I had my time as a club kid, out 'til oh-dark-thirty having a good time, but if your hobby is being out past the witching hour, when the drunks and the criminals are all clocked in and working, don't be surprised to encounter them. Two of the three times I've had to pull a gun were after 0300 in the city, coming home after picking friends up or dropping them off at a club.
