1. Begining of shift.  You don't waste money and she has time to rearrange her schedule, if need be.

2. Say,"Geeze, I hate to see the house get all that money when it should be going to you.  Can we arrange for a private date?"  "Geeze" is optional. I guess blunt and early are my answers.

Tip the manager/bouncer $20 for a personal introduction as "a good customer", so she'll feel confident that you're not LE.

Tip her heavily during her first dance segment - $1 bills just won't cut it.  Two or three $10 bills should get her attention, just make sure she sees that it's not just a buck. While she's dancing, smile and try to make eye contact with her instead of staring at her boobs.

When she makes her rounds after her set, buy a lap dance and afterwards tip her $20 and tell her... "man, that was incredible; I'd love to spend more time with you - do you ever consider meeting fans after you're done for the evening?

Investing $$70 to $100 that way should be more productive than spending a lot more to go into the Champagne Room with her.

But make sure you do all this no later than her second set of the night, or you might find that someone else has beaten you to it.
