Very early hobbying days.....pre TER.
I called an escort service from the local alternative newspaper. A very attractive red head showed up. I handed her the donation. She said she wanted to step out in the hall and call to let them know she had arrived (use her call, I didn't want her using my hotel phone). Of course, I didn't think to follow her. After a couple of minutes I looked out in the hall and gone. A TRUE cash and dash.
Had some unexpected free time in a DC motel a few years back - but no computer, no idea where to look, so I called an agency in the yellow pages (!)
A very hot blonde with an aussie accent showed up. She made it a point to tell me that unlicensed massage was a big no-no in DC and made me initial a paper that stated no massage! Ok, fine. I paid (180), she called in, and then asked me what I wanted to do. I said, 'can we start with a little backrub?' she said, 'I told you, I can't do that'
I said 'Ok, Ok, I was just testing - why don't we get comfortable on the bed?'
She looked horrified. 'No, I don't do that'
'Eh, so.... what do you do?'
She said maybe we could go out for a drink or a bite to eat and talk.
I knew at that moment that my money was gone, so what are you gonna do? We went back and forth for a while, she kept offering me a "rain check" if I wanted to try another provider, but I was leaving in the morning and didn't want to play stupid games all night. So I just told her to beat it.
Here's the good part of the story. I was so annoyed and frustrated, I decided to take a drive; I was going up and down the spokes from the monument to the beltway trying not to get lost, when I noticed a woman waving to me in my rental Intrepid. I slowed and rolled down the window, she walked over. She asked "Are you a cop?"
I was actually thinking, whoa, this thing looks like an unmarked cop car and she must need help
I said, 'no ma'am, I'm sorry, I'm not'.
She asks, 'are you sure?'
'Uh, yeah, I'm pretty sure'.
'well, do you want a blowjob?'
Hah!
decent looking 25 year old black girl with a very very good body and perfect ass. we found a spot and I bent her over the hood of the car and shot my frustrations all over back. cost me another 40.
She said thank you, and didn't ask me to sign anything 
No internet connection at the hotel, so I turned to the yellow pages, what a big mistake!!
I had the same experience as you mrfisher- A TOTAL RIPOFF. This outfit runs ads for several agencies using the same phone number (410) 744-0022.
I can't find a website so no new TER review warning others. They have been getting away with this for years
