Yeah it depends. The venue I go to definitely doesn't have to shut down due to noise (it's in the middle of the city where there's tons of bars and clubs), but I get that every minute of a show costs someone money. I don't think the kind of shows I go to would result in more music if encores were skipped, and it's a good feeling when your chant brings the band back out (even if I know it was planned). But, I understand the aspect of not wanting to be click-baited irl.
