There's Help for Drivers -- in the Classroom (washingtonpost.com) Dear Dr. Gridlock:
I know someone who uses the Dulles Toll Road and does the following: At the main toll plaza, where the toll is 50 cents, he pulls up to an unmanned booth and fakes throwing change into the basket.
Then he opens his door, ostensibly to pick up the misdirected change, and instead picks up the loose change lying around.
Then he throws in two quarters and pockets a buck or two. What do you think of this?

Dear James:
I wish I'd thought of it. Damn, I've been paying tolls like a sap for years.
