My advice is this--Cancel the appointment...NOW. By your own admission, you do not know how to shut up when alcohol enters an equation, and blabbing that you know an escort's real identity is you on your knees in kneepads BEGGING for trouble. Furthermore, I call "bullshit" on your "cyber-sleuthing"....my view is you were actively looking.
Tip to renters--Unless an escort wants you knowing his life story/bidness/etc....keep your nose out of it.
