I think there are two classes of clients who negotiate, one is the out and out cheapasses who don't want to pay full value and want sex for nothing, and the other is the clients who are used to dealing with independent ladies they meet at hotel bars or other venues, who will negotiate a price because the date includes social time and/or a party. I have brought a few American friends to Montreal, and these guys are experienced in the USA and see higher end SPs, but what they are used to is negotiating with indy escorts for a 3 or 4 hour small social party of which private time is just a part of what is going on, as they are also providing social time and drinking with the guys and doing other stuff like maybe a striptease. There appropriately should be a negotiation for such activities which include a longer date, party, drinks and food purchased by the clients. I have told these guys, on our trips to Montreal, that I will negotiate a deal with the agency that includes one price for each girl for each guy for the entire 3 or 4 hours, but once that deal is done, there is NO FURTHER NEGOTIATING. The issue then becomes, in that situation, what if the client wants CIM or Greek from the girl once she is in his room after the party is over. We actually have not had this issue come up, because usually when a girl gets a 3 or 4 hour paid gig and most of the time is spent partying, she is happy to provide great service. All of this is common sense, and I have negotiated deals for me and 5-6 different friends on different trips but it is one lump sum per guy per girl. In these situations you are paying for someone to essentially party with you the entire time. The only problem in negotiating is that if it's a busy Friday or Saturday night in which the girls would be booked anyway, you are not going to get too much of a discount nor should you expect one.
In a one on one situation when dealing with agencies, I had to explain to them the agency or girl's rate is what it is, and there is no negotiation and they abided by that. But on the multi hour gigs, I did all the negotiating and the guys were happy with the deals I struck and they all abided by the deals. I also told them if they didn't abide by the deals I made with the agency, they would never see me negotiate or contact anyone on their behalf again, so they understood they had to play by the rules agreed to by me and the agency.
