Sometimes however, you will get more than you expected. The girl will surprise you in some way. She will do something that makes the session a much more satisfying or memorable experience. If the girl exceeds your expectations, thats when you should tip. At the end of this type of session, you are already thinking about booking a repeat visit.
When paying upfront, I pay the agreed upon amount. I only tip at the end. That way if the experience was better than expected, I know that she took the initiative, it was her choice, and I tip to reward that.
