If you ask a lady to take her photo and she agrees that is between you and the lady.  I believe the ban was taking it a bit to far.  

Honestly if it was such a problem for the provider she could have just said no.

???

If she agreed, I don't understand what the problem was.  Did she tell the agency, you took them without permission? Or did you get caught with the pics?

I don't think you were out of line if she agreed to it.  If you were breakin some type of rule, she should have said something before hand.

This action seems a bit extreme based solely on the info you provided.  Suppose there are many possibilities a few of which might be that the girl actually felt coerced but didn't tell you, agency wanted their cut, other girls at agency felt they would be pressured into doing same, your rep with the agency was already pretty bad and this was just an excuse.... the list goes on... Just move on and forget it... but it does make me wonder how this got revealed to anyone besides you her in the first place.

but hard to know for sure

hopefully they will still let you use them for a reference

you broke an agency rule that neither you nor the providers were aware off.

Maybe the rule is in the fine print. I know of one Atlanta agency that has published the "Magna Carta" and expects its clients to read it in its entirety before calling to book an appointment.

Right....

it is their call.  A provider has refused me prior for whatever reasons, it is her call, you don't have to like it, but should respect it.  This is a very personal/impersonal biz.

IMHO. They have rules and apparently you broke one. You've been a loyal customer for many years and have spent some nice money on them. Apparently that means nothing to them and that's fine. They can run their business as they see fit. I find it interesting that in an economy like this they wouldn't even ask you if you knew the rule or let you explain you didn't know about the rule. Customer no-service. Again, it's their right.

As you said, there are plenty of other options out there and other quality agencies (collective??? WTH???) with beautiful ladies and friendly staff that will be happy to accept your appointments. Move on and don't look back. If you ever hear that they are willing to let you back in as long as you "know the rules" I would politely decline.

Oh, and for the record, you *might* want to consider telling people the agencies name. Not to cause them trouble or anything but there are other guys that like taking pictures. And if they don't know the rule they end up on a banned list also. You haven't said anything rude, insulting or troublesome concerning the agency so giving their name only let's other guys know that that agency is a no-picture type of agency. Just my $.02.

As always, be safe and have fun

It sounds like that was a little harsh to ban you for this reason. Now there are always 2 sides to every story, but from what you have said, it didn't sound like that was a 'known' rule. If the provider agreed to let you take the pictures, that was between consenting adults. If the 'agency' had a problem with it, I think they should've gave you a warning. If you used them on a regular basis and were a loyal client, I think that's kinda screwed up for them to ban you. But as I said, 2 sides to every story... I don't know you, so I don't know if maybe you could have already done something to irk them off before this incident? I'm not accusing you of doing anything else wrong, so please don't take that the wrong way!

If agencies want to make it a rule that clients cannot take photos of the providers, they need to make it clearly known. They need to make it known to every provider, and on their website they should have a list of rules and no-nos. (If this 'agency' even has a website?)
