I once was "forced" to pick up a hooker/drug-addict.
It was raining, she was standing next to my car. Didn't look homeless, was banging on the window, I took down the window.
She said she doesn't know where she is and needs help. I said, "How about we call the police?"
She said, "I can't see the police."
I said, "Why?" - and she said, because I'm high on heroine.
I said, ok - and as I said ok, she actually just got into my car.
Now I'm freaking out. Looking at escape routes, watching her hands very closely.
I asked where she needed to go - she said "HOME" and I said, "Where is that?"
She told me where it was, but wanted me to go another way to get there. I said, "This way is fastest." and she said, "Yeah, but if I go that way, my pimp will see me and we'll have to stop so I can buy more drugs."
So I said, OK.... let's get something straight. You got in my car, high on heroine, and are a prostitute. I feel very uncomfortable right now, but worse - you should be very uncomfortable too because you don't know what I'm capable of. I will take you home, but I will take my way, no stops, nothing.
So she led me to her condo around the corner, I dropped her off.... doused my passenger seat in rubbing alcohol, and tried to shrug it off as I went along the rest of my day.
As she was getting out I told her, "Listen - get your life in order lady! Ok!? The next guy who picks you up might not be a nice guy like me.... he might want to rape you, kill you, and then eat you. Do I make myself clear?"
and then I drove off.
