This is my first post on ECCIE though I've been hobbying for a while.
I am not an escort. I am not paid for a service. When people start paying me, they can certainly feel free to review the level and quality of service I provide. :-)
That having been said, I have NO problem (in general) with backchannel intra-provider information exchange provided it is limited to information of relevance. (Was he clean, did he pay, was he respectful, etc.) I have nothing to fear from this because although I am not rich, handsome or especially hot in the sack; I endeavor to fulfill the basics of being a good client. This information IS exchanged ANYWAY!
But there are two areas where I have concern.
First, though I see few and prefer to repeat, every escort is treated differently in certain respects based upon a variety of factors.
If I leave a tip for a woman, even SHE may have no idea why it was left. For her to tell others I left her a tip might create an unrealistic expectation in others.
The same applies to other things I may do. Because of certain specifics, I gave one provider a full-body therapeutic massage. (I am trained in it.) Now, I'm sure that was fine and she enjoyed it. But I certainly wouldn't want other providers EXPECTING that booking a session with me will automatically net them such treatment!
Think of it as if a provider rendered some service that isn't usually on her menu. Reviewing that could cause other hobbyists to expect it. Not good.
Outside of showing up clean, being Mr. Nice Guy and including the right amount (plus maybe a bit extra) in the envelope; EVERY other aspect of a session with me is pretty much unique to the specific provider and really, IMO, nobody else's business. I'm not getting paid for this, you know -- so Your Mileage May Vary Considerably! Frankly, I suck in the sack the first time with most women; but over time I improve.
Second, sometimes when providers share information backchannel that they think might be helpful to the client; they are not being helpful at all.
In one case, I went to book with a lady I hadn't seen before, and because she had stressed something on her website, in the email I noted that I didn't mind it. By the time the game of "provider telephone" had completed, the fact that I would merely tolerate and accept this got blown into me having a fetish (which I don't have) and created a bit of an awkward moment when I went back to visit a lady I see fairly often.
IMO, and it is only my opinion, information shared between providers about clients should be as limited as possible to factors pertaining to health, safety and business.
Do I mind having such items reported? Absolutely not. I endeavor to be a good client.
But beyond that, I think providers should keep the fact they think a client is absolutely fabulous -- and why -- to themselves.
