That’s such a crime that you can’t. There’s probably a lot of the time it’s just lack of awareness.

I’ll always remember this one store we were shopping in, literally killing time. The workers kept asking if we needed help but we were just looking. No big deal. It wasn’t until we left that we saw the sign and realized it was long past closing. We were the assholes out of obliviousness. I will always wish they were allowed to tell us about closing time

It’s especially egregious because most larger stores have announcements. If my grocery can announce “15 minutes ….”, why can’t that little shop?
