A tough attitude or being tricky, which is a better negotiation skill?
I plan to visit Palace in November.
I have heard a lot about that the girls in Palace tend to be more upselling and asking for extra tips. I'm worried about this.
I have a tight budget, so I don't want to spend more than 50 EUR with one session / one girl.
I will have to insist on paying the fixed price (50 EUR) and reject all the upselling and tipping.
Here's my question.
When I negotiate with the girl, should I just tell the girl with a tough attitude "I will only pay you 50 EUR only! I do not want any upselling service, and I have no extra tip for you either."?
Or, should I be more tricky, tell the girl "If you make me happy, maybe I will tip you or pay more money for your service, all depends on your performance", and still pay her 50 EUR only in the end of the session?
A tough attitude or being tricky, which one is a better negotiation skill to make both myself and the girl happy?
