Worked in one in Boston back in 1989 as a guard.I was 19 years old.Ist floor check-in and medical facility,2nd floor detox and 3rd floor for the so called loonies.Had to help strap a lot of people down.Not nice(aids was always at the back of my mind as it got scrappy and bitey)Detox admissions...
I heard that the vast majority of affairs start in workplace/office situations. I dunno ,but Id be wary of that shit.In the end tho its down to trust......Cheers.
