Was parked 45 minutes in a 2-hour zone. It was a street I'd parked on a thousand times, too. I look out the window of the office I was in, and I see the guy writing a ticket. I ran outside and asked him why he was writing me a ticket. He said I'd exceeded the limit (flat-out lie). It just wasn't possible. I'd been there 45 minutes. I even looked up and down the street to see if there were any temporary "No Parking" signs. I knew it was "No Parking" from 4-6pm, but I got the ticket at 1:30 pm. Dude just wrote it, not giving one eff.
I couldn't even contest it because there was no way to prove I'd only been there 45 minutes. I never paid it, on principle.
