GaGa, you have a pistol in your hands, and no it's not a .22. Not everyone has the freedom you have, and there has to be a balance.
Employment info is strictly verboten as you mentioned. You are dealing with a man's livelihood. I've given this info out once. That was to a long established agency. I've switch jobs, so good luck with the track down. If an Indy ever asked for this info, no way. My references speak for me. No need for additional personal information.
O is trying to find a balance. My advice for her is the more you are connected to your place of business, the more rigorous your screening has to be. If you are providing an incall to a longer term location, you better be 110% confident your client won't show up unannounced or screw you in some other way. Some of you ladies are much too trusting, possibly you O as well. Recently, a lady told me about a client that dashed with the cash. I question her screening, but even more, this asshole knows where you live, at least temporarily. What's to stop him from 'visiting' again?
I'll keep my eyes out for the BSC's, and I hope I have my fellow bros help me out. However, the ladies are inviting someone into a situation that is potentially unbalanced. O understands the privacy issues, and I respect her for that, but privacy is of small concern if she gets robbed or worse.
