I have, but it was a long time ago (like 15 years ago). It was a week day, day shift, at a drink hustle club. I would just sit and talk to a dancer, get a few drinks, tip her for her time, then excuse her once I was done talking with her. Then another would sit down after a few minutes had passed (or whomever I had made eye contact with next). It was a pretty inexpensive way to kill some time with pretty ladies when I worked nights.
It was a very SLOW vibe. Often, the is no music even playing. If you're used to the Fri/Sat night party nights with rain makers, then you might not like it. I found the conversations, light drinking, and front room flirting pretty refreshing & recharging.
If you are at all self conscious and not self confident (since all the staff will be fixated at you at times) or if you have trouble guarding your space then it might feel awkward. Me? I couldn't care less.
