Anyone had a brush with a potential serial killer/wrong 'un?

I have. I was fourteen and in a popular gay bar called The Mars Bar. I was with my girlfriend and we were drinking pints and having a fine time.
We were approached by an older woman who invited us outside for a smoke: of the ganja variety.
We walked down a few alleyways and into a Greek men's club where the occupants were playing cards and drinking coffee. We headed into the back, to the toilets. We all smoked up and a few minutes later we realized this dope was mixed with an hallucinogen.
This woman said she had something to show us. She lifted her skirt and showed us a healed wound on her leg.
She said she was shot.
When she was young and stupid.
Having cones with people she didn't know.
We legged it. Flagged down a cab, got home and tripped for six hours.
