General question. Has anyone had their employment verified by an escort. Most of them required to step verification I do have a review for one verification but need the second.

Some bookers do this, and P411 used to do it at least when I joined many years ago.  

I have NOT done the employment route, but she should explain to you her general procedure.
.
For example, she calls main number; asks reception (or voice menu) for Mr. izzmeblink; if she gets a live person that isn't you, she says it's the dentist's office calling with a reminder about his appointment (or something like that). There are other variations. She should know that the first male voice she hears might NOT be you (you might have a male assistant / sec'y), and should NOT blurt out "This is your fuck toy calling to confirm that you're hard for me." "This is Mr. izzmeblink's assistant. I will give him your message. Who shall I say was calling?"

Or at least she said she did.  This was before I was on p411.  In fact, she introduced me to p411 after.

What the hell are the providers thinking when they pull this type of bullshit?!!  Seriously !!!  We all have to be discreet in this line of work.

High hurdle that many won't cross. But, it was the price of access to premium k-talent.

I got badges!

Sadly Trinidad Silva died in a car crash shortly after filming this.

That's a price that I'm not willing to pay.  
I've managed to monger all these years without ever having to disclose any employment info, and I intend to keep it that way. I'd like to think that most providers and agencies (apparently not high end ones) would be willing to work with a client to verify them. If not, time to move on.

Is No!
The further answer to your question is not even when if Margot Robbie is offering to let me bone her in the butt, Scarlett Johansson is offering to be a 3rd, and pigs are flying on a cold day in hell.

I only hobby with those who conform to what I consider reasonableness in verification..  

LOL

Some years ago an escort wanted to verify my place of employment prior to meeting me.  I told her that I was out in the field and seldom went to the office.  She said that she would call the office and leave a message reminding me of a doctor appointment.  I said okay and gave her the name of a fellow worker who also worked out of the office.  She called, there was a verifiable employee with that name and the receptionist took the message.  Escort was satisfied and I kept the appointment without giving her my real name.

Forgot to mention in my post that the fellow worker whose name I used was young and single.

Intransigence will be the death of them.  Especially when the customer has an alternative to satisfying the prerequisites of engagement.
