A private show means anything from a long sensuous session including fs, to taking you in a private room, extracting a couple hundred dollars, doing a little dance for you, and when you try to touch her, saying, "Oh sorry, no touching is allowed, that would be illegal."
The phrase YMMV was invented for "private show."
There's a little strip club in SF where you go in and pay money to see a girl do a show behind a glass booth. During the show she says, "For $100 (or whatever she thinks she can get) we can go in the private room in the back."
So naturally the guy says, oh yeah let's do that. She tells you to go leave the booth and give the $100 to the guy working there. You do that, and he leads you into the back, into a small room where there's another glass booth . . . and there's you girl.
That's right, the $100 private show is another glass booth room. Of course they get no repeat business, but this place has been burning tourists for years.
