In South Africa, one doesn't pick up hitchhikers. However, I do pick up people from time to time with my three-wheeler. I passed these young men in a township, struggling greatly with a supermarket trolley to get this object (whatever it was) to a scrap metal dealer a kilometre away. So I picked them all up, together with their "loot". It was a moment of triumph for them when we arrived at the scrap metal dealer (see the photo -- you may click on it to enlarge).
