I find public humilation a useful tool in raising awareness. I've mentioned a few times how once someone beat my car with their brolly, here's the full story in all its glory:
I was assisting someone in an education appeal at the civic offices. I pulled into the disabled bay outside, next to a bus stop where there was a big queue of people. I was rummaging around in all my gumph trying to find my blue badge when the woman at the end of the queue approached my car and rather angrily pointed to the disabled sign. I ignored her, as you do. She then came round to my window and started banging on, shouting at me to move my car.
I confess, at this point I had found my badge and could have shown her, but I didn't. I'm contrary like that. I have to prove myself to the traffic warden, not some aggressive stranger who just happened to be at the bus stop. So I ignored her. She got completely enraged and started smashing her brolly on my bonnet and windscreen. I was very frightened but still didn't show her my badge. Nobody does stubborn like an aspie does.
At this point everyone was watching. She then made a point of noting my registration and taking photos of my car. I ignored her and was now too scared to get out of my car.
Then she saw a policeman approaching. She went rushing off, jumping up and down in her glee at being able to tell on me. He came over to my car and opened my passenger door. She stood behind him looking all smug like as everyone else watched the drama unfold.
The policeman picked up the pile of papers on my passenger seat, thanked me for coming, stuck the blue badge (which was on the papers) on my dashboard and we skipped off happily into the civic offices together. Regrettably I didn't see angry woman's face, but I could hear lots of sniggering from the spectators.
