Here's a story I read about in this month's Genii Magazine, then tracked to the Weekly Japan Update. An enterprising (and hungry) fellow visits an eatery, then tells the staff and others in the place that he doesn't have enough money on him to pay for the meal, but if they pony up the cash, he'll entertain them with some prestidigitation. Of course he doesn't, instead making tracks out the door. Apparently he has disappeared some hefty sums of money out of the wallets of those in the potential audiences. The moral? If you're going to be kind to a starving soul, just be kind. Don't expect magic.
