I was in Vegas once on business and fell for the trap.  hot girl hitting on me, late night, wanted to go to my room.  Not to be pompous, but i'm a good looking guy, in shape, so it wasn't out of the norm for a woman to make herself available to me (sorry, just being honest).
anyhow, we get back to my room and as I go in for the kiss, she puts a finger between our lips and says "$300 for a blowjob, $500 to fuck, $1000 for anything."
at first i'm super pissed, but then it dawns on me, I could bang this chick until my dick falls off and she'll never call me, or bother me again.
so I get her down to $800 for everything but anal, end up fucking her good.  she was on top as i was about to cum, she ended up jumping off me, shoved a finger up my ass with one hand, and jerked me off with the other.  all with a titty in my mouth, fucking hot shit.   
 
and again, the best part, she immediately grabbed her things, poured me a drink and walked out the door
