That is dangerously naïve at best.
Most people on this planet are straight up fucking dumb, gay or not.
Thanks for that link. So I guess it’s to make sure the IDs are legit and to enforce bar policies (they flag you if you misbehave).
It’s still really stupid and unnecessary. Especially they aren’t even required to tell you that you’re getting photographed.
