Wanted the VIP? Yeah that sounds bad, just about anytime a chica hits you up for extra money, it's usually a bad thing, and maybe a good time to walk out.
The problem is you paid first, so she already has you, and you just about have to give her the extra $20 bucks if you want any kind of decent service.
I sometimes still pay first, but I'm just about at a point now, if a chica wants the money up front I tell her to take a hike, and just go downstairs and get another chica, and just tell the hotel it didn't work out, and they always let me bring somebody else to the room later. ( If I picked that chica, and she told me about that VIP service, and I didn't pay first, I would have told her to get out of my room! Unless of course that VIP service included at least a BBBJ, DATY, and anal sex)
But it sounds like you got decent service, so that's all that counts. But she isn't suppose to rush you in the first place, but sadly in AB many girls rush you.
If you wanted to save money, you could have counted offered at $50 dollars, since we are still in a recession a girl would be crazy to refuse, although she might settle for $60 dollars, and if you really wanted to save money you could negotiate in peso, as I bet she would go for 600 pesos which is about $47 dollars...even at 700 pesos is only about $55 dollars.
