talking of helping random strangeners, I was riding home along clerkenwell, and saw some dude with a nice old 10 speed walking his bike, I assumed he had a puncture, but on slowing down to offer a pump up, I saw his rear derailleur jammed into the spokes, preventing the wheel from turning at all. Without a adjustable spanner (I usually only carry a hex) I managed to get his wheel unstuck by hand but with chain hanging down with the derailleur still attached, he could now coast, so I towed him (he grabbing the webbing straps of my bag) home to Bethnal Green - we must have been a weird sight.
