20 years ago, I visited SF as a tourist. At a BART station, some guy was wondering around asking for random improbable amounts of change "so he could get home." I probably gave him a quarter, but he saw some paper in my jacket pocket, reached in, and grabbed it. Then he realized it wasn't cash (just a map), and exclaimed "Oh, sir, your papers!" like I'd dropped them and he was helping me by finding them for me. I'm pretty sure he was high on something (or got fried by something that got him high). It was so ridiculous that it was more funny than anything else. Never had anything like that happen to me, before or since.
