What I'm really saying is, why is tipping expected before any type of "reward" is offered. I understand that a girl's room is her castle, but I feel it really makes me feel like there is no respect when a model asks/whines for tips, which I then give in decent quantity, to which her reply is "thanks hun" without even a smile. Obviously I can just make my way to another room, but I still feel like I've been ripped off. I'm OK with stated goals like "500 for nude" etc., I'm really just getting at the whole underlying culture of the thing. Rather than me feeling like I'm some sycophant groveling at the feet of a beautiful woman, I would rather feel like a patron of an adult entertainment show, who rewards that show according to how good the show was. I've tried to bring this up in some rooms and gotten majorly ripped for, but I would rather have a girl put on a how and me tip her as a reward for good work. This is at odds with the prevailing "give me money and you just might get to see a nipple" zeitgeist.
I guess it all comes down to what gets the most tips, and apparently guys like to be taken advantage of. This doesn't really apply to the girls who post in this room, however.
