Are there any standard tipping situations when dealing with an SP? What about if they swallow your sperm without you requesting it? Is that a tipping situation or just part of their service.
Doing anything without you requesting it is really what they wanted to do. Would the girl want to see you again? Hey man she just swallowed your load what do you think?
She probably would like you to see her again for her regular donation. Not seeing her again would probably upset her if she went over and above the normal. A regular steady income with a partner you know, like, and can build trust with can be very valuable.
Normally a greedy SP will tell you everything is extra, and start off with high prices. Be extremely careful of those ones. They are normally the first SP to say "yes yes pay me more!!" when the word "money" is spoken.
The bottom line is all girls have a differant set of rules and prices for their services. The clients also have what they think is fair for each service. One guy might think a service like swallowing is not that important to him etc. The SP can't expect that doing a unrequested service means anything to you.
Some services are not really given at any price but rather because they wanted too. YMMV is a term used because of these situations. It happens when you really "click" with someone.
Lets face it girls give up sex everyday for free. Some feel they need to get paid a lot for every little thing. Others are extremely happy doing something they love and getting paid highly for it.
A escort that charges less can give you just as much if not more of a good memorable time. Those that have bucket loads of reviews and many guys after them charge more because of the demand is so high. However they are not so picky over the little things. The normal extra would be greek more then anything.
