There's not much more annoying than returning to your car, than finding a "love note" from the city affixed to your windshield. You know the one... "We'd LOVE to have some money from you!".
But it does become just a touch more annoying when you've already put a bunch of quarters into the meter, prior to that ticket, and then missing the cut-off by a few minutes, only to find that ticket.
It seems to me that the city should take into account your initial investment in legal parking and deduct it from the amount of the ticket. Right? Right?!
