Yea, really depends on where you go. Clubs can charge whatever they want. One local club here charges a $20 cover to get in. I pay $10 though because I'm in the "service industry" (I wait tables). At this same club, the girls have to sell something like 7 or 8 drinks to meet their quota....which means you have to buy them however many drinks they talk you into for $5-$7 each. Then theres the lap dances. The girls at this club can charge whatever they want. Some girls charge around $20, others charge $40+. Oh, and you have to pay the guy watching the lap dance room $8 on top of that, every time you go to the room. LOL. I personally would not go to a club unless I'm planning to spend a minimum of $100.
Clubs can be fun, but expensive. Then you have the guys who lurk in the back of the club away from the stage that never tip, or buy dances. Dont be one of those guys. They dont have a good image.
