Indeed! Usually it's a passive-aggressive comment that still paints you as the guilty party.
I still remember, 18 years later (as it was a proud victory against an inner London council that was VERY notorious for nefarious parking fine practices) when I got a solid appeal upheld, the cancellation letter I received stated that they were "letting me off" as it was "my first offence"! Initially I was fuming and was going to pursue it further as they were so rude, but I decided that I had the result I wanted and I should spend no more energy on it.
