This poor horse has been beaten a slow miserable death so many times that it's not even fun anymore without anyone convincing anyone of anything.
If I walk on to a car lot because I like to roam around the new cars, and, although I don't, I might, I think that I'm doing what is available to me as a potential customer and, even when I actually shop for a car, I don't buy everyone that I look at or even one everytime I walk onto a lot. That's inspite of the salesperson wishing I would or assuming I should, even if they think I'm a jerk because I don't. Even if they make up really good stories about how sick their spouse is, etc and assume that the stories make me more obligated to buy a car.
And while the dancer is not a retal product, the dance is a retail servicce that's being sold, just as the car salesman is not the product, but the car. Until there is a 2 dance minimum or some such thing, buying the dances after entering the club remains a choice of how or whether to allocate those scarce resources.
The dancer's choice is how or whether to allocate her time. Just as a car salesman might want to keep you locked up in on of his hateful little white rooms for hours on end, a dancer may choose to stay with a customer for as long as it takes her to make the sale or give up. She can choose to ignore the ones who have a history of not buying.
As has so often been pointed out, feelings, beliefs, wishes, and expectations aren't really part of the equation.
