QYB, I understand where you're coming from about wanting to help out and I'm sure it was a rational and balanced approach, as you said -- but unless you have another rational and balanced mind on the other side of that helpful advice, you can expect to be met with a defensive ego lashing out because the self-image has been threatened. Hopefully some points you made will sink in with some introspection, but that's the arrogance of youth... what can ya do?
I see so many bad business decisions made like this, but I think too many girls don't see this as akin to running a small business. Yeah, they can do the "detached, just in it for the $$$" thing well, but I mean treat it as a business as far as marketing, customer relations, etc. Most of the girls I meet are savvy enough to figure out (or ask if) I'm on TER and try to make sure things go well (not that I use it as leverage, but I'd rather they know than pull out my Secret Shopper badge on 'em after the fact). I've also sifted through a number of reviews where the first one or two are bad, then it looks like they straightened out and got better reviews moving forward, so I think low reviews can be a strong teaching tool, especially when the phone stops ringing.
I would definitely leave a review, but not as retaliation, just to let other guys know. We all want to leave glowing reviews to help the ladies out, but you also need to help us guys out and give a heads-up when you get into this kind of sketchiness. The first girl I saw in this hobby really sucked (and not in the good way), but I didn't leave a review 'cause I didn't want to hurt any feelings and it was my first experience so I thought that was just the way it was. A few months later, a review similar to my experience popped up and the guy was pretty disappointed, so I kinda wished I'd posted and saved him the grief.
