A common sight in Lisbon - car parking 'attendants'. If you try and park in downtown Lisbon one of these guys will appear and 'help' you. I've always payed them as I assume the implication is if you don't something might happen to your car.
I guess most of them are junkies and this means they get money without doing anything too bad. Some of them do actually keep an eye on the cars as well.
