If they're SPs they'll let you know.
If they're not and you're just looking for someone to go for a drink with or the like, then it works about as well as asking out the barista at Starbucks.
If she escorts she will let you know very few of them do .
He would have better luck with the barista at Starbucks. As west woody said
She will have had plenty of offers already.
What most likely will happen is
she will say it is x amount for a private dance and ask you if you want to go into the Champagne room and as Chris rock says their is no sex in the Champagne room.
I personally hate strip clubs they depress me. If you want to know more about the attitude strippers have towards customers read strippers web particularly the "hustle hut" section.
I have never tried to "pick up " a stripper but anything I have read on the subject has said two things 1 never pay them money in the club and 2 It will be far easier trying to pick them up outside of work . Like a late night coffee shop or restaurant they may go to etc. You have to separate yourself somehow from being a customer . Very hard to do if you do not know them or someone they know outside of work.
Going into a strip club to try to "pick up " strippers
Its like walking into a restaurant and sitting down at a table and then trying not to order food in order to try to pick up the waitress .
