Am wondering at the part where it seems that $400 was his base rate for just being there, and extras on top of that were negotiable, was that right? If so, its not beyond the bounds of comprehensions for the escort to assume that all the extra stuff you did amounted to another $400 and therefore if you wanted a repeat performance he assumed it would be the same fee? I know that might be a stretch, but its also a stretch to give 100% tip. I feel if you give that amount of extra on the first meeting, you are shooting yourself in the foot for any subsequent meets. For example if the escort didnt get the same amount next time he might have wondered what had gone wrong, and it could put a damper on all subsequent meets. Seems like communication was maybe unclear
