Well, on codementor you can give a refund. And that would erase the session (and the rating, if you received one) from your history. I think it's better than tipping. Tipping, at least to my European ears, sounds like this voluntary thing as opposed to paying for a service. BTW, what happened to your service? Or, probably better to ask, how far did you get and why did it fail?
