well..it depends...if i see that this girl is brand new out of box,i'll try to slip $40 first...uhmm that would be 4 $10 bills..believe it or not it works better with more bills on hand...
and if i see the girl looks like a season player,i wouldn't just give it away..i would work on it first and make sure she's down for it,then it will be around $70-80.
