you park like an asshole!

I guess asshole parkers are a way of life, and vandalism, while tempting, is not a good idea.
leaving a flyer disguised as a parking ticket ( if you have little envelopes) feels like something positive.
I keep some ‘you park like an asshole’ print outs in my car.
you can tick the appropriate ‘offence’ and even take a picture and post to the website with a tirade if you like.
