A word about paying for a dance.  Always pay cash if possible.  Why?  Because if you use your credit card, they usually charge you a processing fee of $5.  This is a rip off to me.  Also, you might want to offer her a barter deal for a dance. Offer to wash & wax her car, change her oil & filter, lottery tickets, jewelry, gift certificates, any services related to your business, etc.
Accept  this as something you have to put up with in topless clubs.  You will constantly be hustled for table dances!  Don't hold this against the topless dancers.  This is how the dancers really make good money.  So, if she's not doing dances she's not making any money.  They have bills to pay just like you and me and she will spend most of her night hustling men for dances. 
Always  remember  that you're under no obligation to buy a dance from her.  If she's really crazy about you, she will even dance for you free.  If this happens, you've got a real good shot at scoring with her.

Back to the dancers soliciting you for dances.  As you are sitting at your table you will be approached by dancers with their standard line of, "Would you like some company?"  If you say, "yes" right after she sits down, she will hit you up for a dance.  You can stall her with small talk after she joins you, but eventually and real soon she's going to ask you for a dance.
So, what do you do?  Always say, "I'd rather buy you a drink and get to know you better.  I know the ropes of your business, so if you need to go make some money, I understand.  Just come back and party with me after you make your money."  If she never comes back, you'll know she's not interested in you, because you won't buy a dance.
