My experience as a barista was that the nighttime customers would just refuse to leave when it was time to close because they “weren’t done yet” with their conversation or their homework. It was a really uncomfortable situation & can make you feel unsafe when someone does that. That one latte they ordered two hours ago isn’t (IMO) worth that hassle.

I was an employee and hated it. Too many drunk people coming in all night long, especially on the weekends
