I have 24 +ve feedback, recently did a punt and a field report, it wasn't published, but the lass left me +ve feedback, so it does happen
I now prefer when they don't live feedback, as it looks like I have nothing better to do than go round shagging
You will find most WGs will want feedback so people can see they are good, recent, etc
Those with zero or don't allow you to look at feedback - IMOP - walk away
