I think I've only written on eno..and that was a BP bait and switch. If I spend time with one of the girls and it's not perfect, I generally just wouldn't write the review. If I had to leave for some reason, then I would but a "good" time is SUBJECTIVE. If I put objective statements such as CBJ or No CIM, that's objective and should be enough for other guys to make a decision on whether to see a girl. I generally write a review when I had a good time... and I want the girl to benefit from the good job she did with my visit.
Bottom line you don't have to be a dick when you give a no, you also are under no obligation to give a yes. Just the facts thanks, and we can all make up our own minds.
