You make a good point. Yes in a perfect world. But I'm going to take the other side for just a second. And I'm not usually one who bends over backwards to excuse bad escort behavior-or at least I think I'm not. And in this case before I proceed, I'll state that I've never met Lance. But my thought is that Lance probably receives 100's of emails or texts. I can readily see how a snafu might occur if you are only relying on emails or text.
If a scene isn't "ordinary" as in I want a strong, muscular bottom (or top) who kisses, spits in my mouth, murmurs sweet nothings in my ear, etc etc, and the special circumstance is a sine qua non for the client to have a good time, then I think I'd mention it at some point either right before or during the 1st few minutes of the meeting.
