whats to say that the parking inspector wasn't having an off momnet, wasn't concentrating... and wanted to book the ford parked behind you, but whilst writing out the ticket glanced forward at your car parked infront of it and noted your rego down... once it was printed he realised he f**ked up and then just stuck it on your car?
as once a ticket it printed, it cannot be reversed, f**kup or not.
