There is probably a good reason for parking attendants to behave like rabid monkeys from hell, and if I wanted to, I would certainly be able to sit down somewhere on a spike mat with my hair on fire and listen to the explanation, but I have more important things to do. Like sitting on a chair in my kitchen and watching the color of our newly painted wall dry.

Get change for a 10 euro bill. Get some Blu-Tack. Attach small pieces of Blu-Tack to the backs of coins and attach them to the side of parking meters. Make some poor guy without change happy while making a parking guard angry. Two birds with one stone.
