I had this but with massage.
I had someone text and ask about male massage. When I called the number, it was a man which didn't phase me. We arranged an appointment time but then I realised he was coming from the next city (20 miles away) which made me wonder why.
And then he asked what my name was and said that "I must be good at the job in hand."
Alarm Bells!! I thought I may be reading into it but after the phonecall, I got more texts saying he couldn't wait for his appointment etc etc so I text him to say I was cancelling his appointment due to his behaviour.
He then even had the cheek to say, "Ok sweetheart, you know where I am if you change your mind xx"
Mad!
