I agree with you that it may be a good strategy to barfine early for st in order to get a good price. For lt i would tend to think it's the contrary. Girls may expect to meet a generous customer at the beginning of the night, and then lower their financial expectations.
One more comment: except in rainbow where i had to negotiate a bit, in the other places i did not even negotiate. It was like: you do long time-yes-i give you 3000-ok. I had the feeling it was the most frequent price for them. Maybe i could have bargained to 2500 because of low season.

Another factor that may play a role is how much money the girl thinks you have. I remember a regular i had at a good price and it was absolutely no pb for her. Then she found out that i was not poor and asked for more money. The argument was not"i am worth more money", but "i know you have money, you can pay more". :-)
