In the local clubs around here there is theoretically a mask requirement for anyone who is not seated, but it is not especially well enforced. Indeed people are wearing them while they walk into the club, but then most of those masks disappear until they leave.
This extends to the bartenders and dancers. Many dancers are not wearing them at all and most of the bartenders have them pulled down under their chins.
But then every so often I will see a dancer clutching that mask for dear life. After ample experience dealing with dancers on both ends of the mask wearing spectrum, I have found the ones who ditch them to be a lot more fun. Heck the girls still wearing the masks are often also afraid to even get too close.
I have a theory that the girls clutching on to those masks now are the same ones who were the most uptight pre-COVID. But whether this is true or not, the whole mask thing has become a very reliable indicator for me and I will often just refuse their company before they can even sit down. This has made my search for a fun gal even more efficient than it was before this whole mess began. Nice!


speaking of clear indicators...
i was in a bar in thailand a while back. there was a thick red (or was it yellow?) line dividing the bar into two halves. the girls on either side would stay on their side, and they wouldn't cross over to the other side. i asked the bartender what's up with that. she pointed to one side and said "butt sex", then to the other side and said "no butt sex"...
