Well, in more "liberal" cities, you can find a club where literally _everything_ is on the menu in the (very private) VIP room. Though if that's what you're after it'll cost a lot less to find a good escort.
I just moved to a new city, and in one of the clubs the dancers will list their "menu" while wandering among the tables.
Usually, a "no thanks" or "I'm sorry, but you're just not my type" works.
In more extreme situations, where she just doesn't get the hint, I've used something like "I realize this is a financial situation, and I wouldn't be offended if you went looking for someone who was going to pay for a dance."
