Doesn't seem that much less than one a day some prossies are very good at getting punters to leave feedback either by asking at the right point or some profiles I have seen offer a discount for good FB. Of course there are always fuffies as well who would actively offer good feedback hoping to gain special favours. Most unlikely of all perhaps the prossie does give a good and professional service to the punter. Rare but it does occasionally happen.
I saw an wg last year and she would sometimes say don't leave me feedback as you have seen me quite a lot lately, most of the time i would just text and make a booking without making a booking request, I would probably make a booking request 1 out of every 4 times I saw her, thinking back i don't know why i did put in booking requests, she gave me no special deals nor did i expect it, sometimes it's just nice to write it down. On one occasion she told me not to mention a song that she had played during a meet when i was going to leave her fb because it was special to us (Her words not mine)
There was another time after a threesome she said dont leave fb because she felt as though she had not done much during the threesome, I mean she wrote nice fb for me, what did she expect me to write, ' lazy cow crap effort what a waste of money'
Sometimes threesomes don't work out, but I left nice fb because I felt she had given a good service.
