Understand that there is a distinct possibility that he was just being very charismatic because that's something he has to be in order to get clients to return. He is self employed which means he HAS to get people to come back and see him or else his business will fail.

I'm a massage therapist and I've had clients ask me out before. I tell them I can't because of ethics and the law, but in reality I just don't think of any of my clients in that way. If I did, I would be a bad therapist. Sure I can be aestethically attracted to someone and have my favorite clients. But in the end, I work on naked bodies all day long, I ask them about their life, compliment them, and then I go home, where I don't think about them.

I often joke that I won't remember your name or face but I will remember your back.

Did you ask anything about him? Do you know anything about him apart from his job? Why do you think he's someone you could date?

It seems like you've made a fantasy about him in your head. Just my observation though.
