Free Parking Metre Tickets
I found out about this last night. You know the parking metres that spit out the tickets that you place under the windscreen? You can fool those machines and get free tickets. First, stick in a 10c coin. Next, get a $2 coin and insert it while hammering away at the cancel button. What should happen is that the $2.10 should roll out, but the parking meter will still register credit (it should say “overpaid $_.__”). Press the button that prints the ticket. Voila. Apparently if you roll in 2 $2 coins really quickly while pressing cancel you can get $4 credit, but I think that requires some practice.
