There's a fine line between night clubs and bars (and a venue can operate as both, depending on the night).

Functioning as a bar where people come in, drink and eat - generally not checking ID's at the door.

Functioning as a night club, generally checking ID's at the door. Almost no places I've been to scan ID's. I'm also middle aged and not going to night clubs hardly ever. Pretty much just a couple concerts a year in the big city. Those venues scan ID's.
