"This was a new one for me. I'm a simple guy." Ted, your tastes is the scene may be simple, but your reaction in this case was quite elegant and imaginative. Some, hell many, in this day and age, would have made it confrontational and asking for a partial refund, etc. etc.
In my experience over the years, but not in this century, during the during the days of responding to grainy B&W print ads of independent Mistresses, I had two appointments with ladies who either who misrepresented themselves, or were obviously high, or both. In two cases I politely and quickly excused myself, leaving a tribute behind, not so much out of politeness, but to avoid a possible confrontation.
With the third case it was obvious the lady misrepresented herself in her ad. I found out when meeting her she was a former athlete/model from Europe, who was then an interpreter with the U.N. But the grainy picture she used looked like she was in her early 40s, my age then. The picture had to be from 20 or so years before. At first glance you could see that she was probably very alluring 20 or so years before, and she was quite charming, so I didn't drop the tribute and leave. Instead I decided to at least sit down and chat with her. When she was ready to start the session - her being the Amazon capturing Tarzan - instead of leaving I suggested we do a "next door neighbor" scene, a seduction or peeping tom deal. (P.S. - In my final session was with Belle de Jour, my first Mistress years before, she was still fit and younger looking than her 70 or so years. Maybe because I knew her so well and she looked ageless to me.) With this lady I remember hand spanking, and a bit of seductive teasing was involved. She was pleased at the end and gave me a big hug when I left and I felt better about myself on the drive home.
