Odd request Sukotisshu and difficult to accept at face value.
I wonder if you are asking the question as a general enquiry or with particular bookings in mind...
I think you're reading WAY too much into it.
I don't want to collect anymore feedback. Period.
My reason for this is because I don't want to advertise how often I punt, or how many I've punted with. I am, however, happy to leave feedback (i.e., leave a record of my booking on the WG's profile), so it's not a case of me wanting to hide that I have booked certain SPs.
Anyway, judging from the replies I've had so far, I have to assume that the ONLY way I can leave (positive) feedback AND ensure that the WG does not leave feedback for me, is if I make sure she deletes the booking from her end after I've left my feedback.
