How do they stay in business when it's so slow there?

I was in the area and came here on a Friday night around 8:30pm. Good sized parking lot. This place is BYOB. There weren't many cars in the parking lot. It was a $20 door entrance fee. They checked my ID. They allow smoking. The one older bouncer was a chainsmoker. I'm not a fan of cigarette smoke. This place is decent size and has high ceilings. It's a big main stage with 2 poles. There's a little section where they sell water,juice and other non-alcoholic drinks. They also sell food/snacks. I bought a fruit punch for $3.

This club was pretty dead. I think it was me and maybe 2 other customers there. There's a mix of dancers here. Some Spanish, some white and some black. The chairs are very comfortable. A Spanish girl came and sat with me. I don't remember her name, it started with a N. She was telling me how it worked there.

A private dance was $20/song plus tip to the dancer, plus there's a jukebox that's in the small room with a door that you need to put $2 to play the music. They have a big champagne room, they have 15min ($80 to the club,plus tip to the dancer), 30 min ($160 plus tip to the dancer), 1hour($320 to the club, plus tip to the dancer). They allow the dancers to do dances on the main floor (which I think all clubs should be able to do, that way you can get a feel of how a private dance is going to go and get warmed up and get in the mood).
