Harkens me back to this weekend, when someone had taken a crayon and written on the side of a cardboard box "No Parking, This side of Street". Then he was out yelling at yard sale goers at his neighbors' house-"Can't you see the sign?". I got there, he was saying this to a lady and her kids, and she told him-"Can't you read the local ordinances? You can't enforce such traffic rules without authority!" Good on her.
I like car boot sales, the people attending are so thick!
We had on that used to park on the pavement outside our house, and delightfully informed us that we could not stop him as he had a right to do so....on video
Shame the Police disagreed, and issued an FPN
He also managed to highlight an issue for locals, got picked up by the local press as an example, and we now have between 20 and 30 parking fines issued some weeks.
