What all do strippers do to you in a private lap dance?

Me and my hubby have been to stip clubs many times, but have never got a private lap dance, or a dance in the vip room. what all do they do in there? how do they dance and stuff, and for a couples dance how do they do that? one get the dance and the other watches or do they dance for the both of you? i like to be prepared on what to expect if we go down that road soon
