In my experience - DC strip clubs are a waste of time. I was there several years ago on business as well. I was staying in a Hilton - and my room had a view of a strip club - so I thought I was going to have a good time. It wasn’t good at all.
The clubs are such that you watch a stage show. You tip the dancer after the show when she comes over to collect/visit.
But there was no contact. No lap dances - no booths for private dances - nothing.
I thought that I just hit a no action/low mileage club. So I walked several blocks and found another club. It was the same. Finally, I asked a dancer. She told me that they don’t do contact dances in DC. However, she told me that I could pay her to sit with me and have dinner! I was thinking WTF? I can buy dinner for a civilian - and not get laid too -
