“Without warning” they were asked to stop, and frisked. I’m a small dude, and anytime I’ve gone to a bar/club in the past 12 years that has a rather large crowd - I get frisked as well. Or the security guard gives me and ocular patdown and asses that I’m not a threat. Honestly they were probably looking for alcohol nips.

It’s standard, but most places don’t frisk women.
