He actually checked the wrong box. But even if he had checked the proper one (meaning the one most likely to apply), then I was squarely in a (legal) gray-area.
Two weeks later, there was a fresh coat of yellow paint on the curb next to the spot where I had parked. Can't park there no mo'. :)
I remember people trying to get out of speeding tickets. The judge asked, “When was the last time you had your speedometer calibrated?” LOL!
