All my my punts have been with AW girls and usually I leave feedback, two brilliant punts got a field report
It may, or may not, be connected, but I usually submit a booking request before the meet and mention at the start "if it goes well, we can leave nice feedback for each other".
Luckily for me, on all those occasions (bar one 'average'), the punt has been 'good' or 'very good'.
On 3 or 4 occasions I have failed to follow this procedure, the punts have been the worst I've had.
Coincidence? Possibly, but it makes me wonder.
Edited to add: I never bring a gift so that isn't necessary to gain good feedback.
