I have done this before, with a zero-feedback newbie. Her profile appeared, disappeared, then appeared again - I suspected that she was a bit hesitant about becoming an escort. So I offered her £30 just to meet in a pub for a chat.
It worked, we chatted for about an hour, my suave charms won her over, I had a good punt about a fortnight later, and she stayed on the game for about a year.
