Do the normal club dancers do more when there is a feature?

I was at my favorite topless club (nearly all the clubs in my area are topless) when they had a "feature dancer". I guess they have them on occasion. This was the first time I had ever been there with a feature. Anyway, I got dancers from my usual dancers, and one from a newer dancer. Anyway, three of the four dancers that I went to the back with did at least a little more than the club normally allows. I was wondering if anyone ever noticed that happening when a feature was at their club, especially when features are not the norm.

BTW, the feature was a complete skank. I was so not impressed by her.
