If you are trying to make sense of strippers and their actions/words, then you haven't clubbed enough - and why most experienced SCers are direct w/o being rude - it's a business transaction, you're not courting her for a long-term relationship - most dancers are clear on what they want or don't want; they want as much of your $$$ as possible while hopefully doing as little as possible in return - it's up to you to get what you want; if you leave it up to the dancers 9 times out of 10 you get an empty-wallet and perpetually full-balls.
One never knows when a dancer will change her mind about something - one day she can be a total prude, another day she may decide to fuck the shit out of you - trying to read dancers is usually as successful as timing-the-market (probably less so) - dancers and custies have different agendas/needs in the club.
If the club does not allow extras, then it's a mute-point for the most part except for possibly OTC which usually has a pretty-low success-rate and often requires building some rapport over several visits but still no guarantee (OTC is more of an art than a science).
Bottom-line "wondering" about what a dancer says is not a good strip-club strategy - if she asks what you want then tell her what you want - if it's a club where what you want is not allowed, then either work within what the club allows or save your $$$ and find a better venue for what you want.
