Before Rudolph Giuliani was elected mayor of New York City, the Big Apple was overrun with squeegee men.

These panhandlers would come with dirty rags and try to wash the windows of cars stopped at red lights, without permission. Usually their so-called cleaning left the cars dirtier than they were to begin with. Still, the squeegee men demanded payment and would stand in front of the cars they’d just dirtied until they got their money. After all, they’d done the work, hadn’t they? And if you wanted them to move, you’d better cough it up.
