It is entirely a matter of choice, between two different types of experience.
The talking / foreplay etc. does take up a good part of the hour. With a SP it's in private and at least one can converse without having to shout over the boom of stripper tunes played over a cheap system.
Sure one can have a good time in a club, chatting with the girl etc. One time I had this chick sit at my table, I knew I would be getting dances so I bought her a drink and let her start working ... she was all over me, we felt each other up and I even slipped in a few fingers while noone was looking. We played around for close to two hours, with a good half hour in the booth, excellent grinding, very liberal dances. Total was 50 dances 25 drinks 20 tip - worth it, damm straight!
