At one of my DCs schools there is one parent that persistently parks on the yellow zig zags outside of the school. She doesn't live that far away but equally it's too far to walk plus she's usually motoring towards the school five minutes before school finishes. My thought is "why don't you get your knickers out of yer bum and get to school 5 mins earlier to get a 'decent' parking space'". But clearly she thinks the zig zags are there for her benefit.
I'm not quite brave enough to confront her face to face. WWYD?
