I have been pickpocketed twice in my younger years by young BP providers.  One was during a BDSM session, while I was blindfolded.  The other was after the intimate part of the session was over, and I had left my clothes unattended to use the bathroom.  I was not a member of any review site at the time, but I guess it hardly matters since you had the same misfortune from a fairly well reviewed provider.  

These days I do not go into a provider's incall with a lot of money other than the donation.  Having said that, I only wish that I would listen to my gut instincts more often, but it is hard to hear them over the desire of the little head.  Damn horny male biology can be a bear to deal with at times.  

Look at the bright side, okay maybe at the not so dark side, you at least walked away with your life and well-being intact.  It's a small consolation anyways.
