My first punt, was with a chosen lady who ticked the boxe's I needed. I was new to AW and didn't have any feedback, so she didn't know me from Adam.
I was in for an incall to hers, so she asked for a small deposit via paypal, it wasn't on her profile , but she suggested it in a PM.
To make the payment to her paypal account, of course this disclosed her real name, but I guess as I was going to hers anyhow, perhaps it didn't matter.
Long story short, I made the payment, paid the balance in cash when I arrived, and had a great time. And have been back several times since, she is my primary regular!
Personally , I wouldn't get to hung up about it, but it does rather depend upon the WG, this one is truly professional in all ways, I guess I wouldn't be so keen if she were an EE!
