Was driving home down a fairly dark, rural bypass (single carriageway) and just managed to make out up ahead someone trying to flag down a vehicle. A dangerous thing to do; as I mentioned, it was dark, and the person was walking in the ''wrong'' direction, wearing dark clothing, there is no pavement and the traffic is fast on that stretch.
Being the good samaritan, I stopped. It was a young 20-something girl who, as it turned out, was trying to make her way to Derby and was a little bit drunk. I told her that I wasn't heading that way (true) and that I was nearly home (also true). I suggested that she needed to get over the other side of the road, where there is a path and walk down to the pub which was about half a mile away. She started getting verbally aggressive then because I wouldn't take her to the (rough) part of Derby she wanted, and she stormed off.
I carried on my way but worried about if I had done the right thing by not giving her a lift.
