Never done it, just a possibility that occurred to me. Clearly there are lots of issues. 1st one being the dancer agreeing to it. It's probably safer than going to a custy's home/hotel, but not as safe as a (well run) SC. She would want an amount somewhere in 3 figures, depending on how popular she was.
If you did it regularly, the sex shop would figure out what you were doing. Maybe if they were making enough money off you, they would consider it worth it to let you use the booth. They probably would have to maintain plausible deniability that lap dances were being provided. So you couldn't overtly negotiate the "rental rate" of the booth.
For custies with less money, they would have to form a group, that the dancer would attend to in the booth one after another. But that would be even more in the face of the people running the sex shop.
