Ethically questionable

Came here on a Thursday night. There was free parking on the street next to the meters (Meters were free). The entrance is a glass door with some neon lights that shine through and you can see some stairs. It's not conspicuous from the street but it's obvious you're in the right place as you're walking by.

As you walk in, you arrive to the front desk. You pay the entrance fee and you walk into the bar area. When I walked into the bar area, I see like 14 old men (in their 50's and 60's just lined up around the bar (even though none of them had drinks) And 3 girls sitting on a bench across from the bar. These old men seem to be min-maxing their money. Just loitering in sadness until they see a girl that worth their precious money. There were guys that were just there for an hour without getting anyone.

I got 1 girl. She was there and she wasn't the best looking but I thought might as well. She spoke very little English but we made do. We danced for a bit and I took her back. Paid her $5 tip
