Yeah, this is sadly common behavior everywhere.
As a guy who dated a bartender for almost a decade and waited around for her to close up shop, I could tell you stories that would make you ashamed to be part of the male sex. (if you identify that way)
The only time I had to get physical with a "patron" was at an isolated lakefront bar in NY. It was only the three of us there at last call, and the dude followed my gf at the time into the women's restroom.
If you see something, the best approach is to indirectly disrupt or call attention to the situation as others have mentioned.
If you are even "borderline" on this yourself, clean it up right now.
