He sounds like a real puzzle. The touching of the arm, the eye contact when you say he was aware of your gender immediately are unusual. It takes all sorts in life, says I with a clear sense of irony.
He wasn't put off though, on several occasions too, so a nice experience with a person unknown.
I had a guy ask me my name in a pub. Once he heard my voice, he did an immediate about turn. So you beat me hands down and with repeat visits.
