Inexperienced strip club patrons need to understand this. There are usually two components to getting into a strip club and sitting down. One is the admission fee and the other is a drink fee. When a strip club offers a free pass, that only waives the admission fee. You still have to pay for a drink to get in and sit down. In some clubs, the fee for both are collected at the entrance. This is where inexperienced patrons feel they've been mislead. In other clubs, you pay an entrance fee (cover charge) to get in, but then as soon as you sit down, a waitress approaches you for your drink and you pay the waitress.
The second sentence in this review is a common complaint from customers who don't understand. See:
He only got half of the normal $20 admission/drink fee waived. That was the admission part. He didn't understand that "free admission" still means you have to buy a drink.


Other classics are the "free dance" which you might think would be normal length, but which is really 30 seconds or so, ("come on, we said 'free', didn't say 'full length'). "3 for $40" (also reduced length). "Buy a champagne room and get five free admission passes!" (which will expire this Friday, but, of course, you were going to visit five times before that anyway).
I bet they hire guys like Rick-boy-Dugan and txtittyfan to come up with gimmicks like that and think they are oh-so-clever with their disenguity.
