For a number of reasons men simply don't publicly expose mediocre service via reviews. Perhaps it's because some guys don't do this very often, so the mere fact that they're with a naked women seems like a miracle to them. If she puts her mouth on his dick he's in ecstasy, even if she's not very talented or enthusiastic.
Outright bad service is rarely reported, because (1) most guys don't know what good service looks like in this business; (2) a lot of guys are married and can't risk pissing off a girl or an agency; (3) many men are "white knights" who want to win personal favor with the woman by talking her up.
And also the opposite effect occurs. Let's say the client is a jaded, experienced whoremonger. That type of individual will not write a bad review because even if he's shorted on the time, even if the girl is distant and cold, this type of client knows that the girl and also probably the agency owner are single moms, women doing their best to make it in a tough business, and he doesn't want to hurt their business and end up feeling like a mean heartless person himself. So you have your bad session and move on.
Therefore there are very few bad reviews, even when deserved. And often mediocre service gets reported as good. Because in this particular industry if there's any service provided at all, you're already ahead of the game versus getting totally ripped off, which can and does happen.
You can't even get guys to agree on the basics of good service. If you pay for an hour and she's out the door in 20 minutes, some guys will report that they had a fabulous time -- which they may have -- because they just don't care abot the time. The next guy who sees the same girl or agency gets ripped off, because he was expecting an hour of company.
Because of the intimate and personal nature of services rendered, this will always be a ymmv business. I do wish more guys would expose bad service though.
