Punt however was terrible. I can't review something that didn't happen.
Depends on the reason why it didn't happen. You can review if it was booked and she either cancelled on you last minute or you walked since she wasn't the girl you expected or didn't offer services that were advertised.
Some of us don't have the vast experience that you guys do, so we come to this forum for help and advice. That's what's it's here for isn't it.
Actually I don't see it this way. This isn't a free concierge service. IMO spongers can piss off. It works on the basis that punters should share experiences for mutual benefit. Doesn't matter if you punt a few times a week or only a few times a year, if you share reviews or help other punters out in some way, then you'll be respected for it. Furthermore, folk will be more willing to help you in the future. If you only ask questions, and never contribute, then you'll get a hard time.
