The first couple of girls on AW were very keen on getting feedback and I was happy to oblige. Then there were a couple of great meetings where I left feedback but didn't get any back (Initially, naively, I was concerned by this. But now I realise it really doesn't matter).
Then I saw one girl, had a great time with here, she emailed me and said she wanted to leave me feedback but she'd messed up and only a couple of letters appeared. She asked me to put another "pretend" booking so that she could leave the full feedback. She duly confirmed the booking and left me some nice feedback as promised. I thought that was quite a nice thing to do.
