have you ever picked up a hitchhiker or hitchhiked yourself?

I picked up a hitchhiker once. It was in around 1987 and there was a young man in RAF uniform hitching along a fairly quiet country road when it was getting dark. The uniform gave me confidence and I had no reason to be concerned. I was able to drop him off at a convenient junction. For all sorts of reasons, the military don't go around in uniform off duty these days and I wouldn't stop to pick up anyone when I was driving on my own anymore.
