Double Yellow Lines Again

I was on my way to the paper shop to buy the latest B&R - and I rounded the corner to find a car pulled up on the double yellow lines, just on the junction. The driver, not a young lady, obviously hadn't noticed that there was a car waiting behind her, unable to get past - it's a very narrow road there, hence the double yellow lines. As she got out of the car the man in the car called out to her.
"What?"
"It's an offence - double yellow lines."
She started to say that she was only nipping into the paper shop - but by this time two or three other vehicles had pulled up behind the man in the car, and I cheerfully joined in by pointing out that she was in the way.
She got back into her car, and before she drove off, said: "All those other cars are on the double yellow lines, too."
This was true - but their drivers weren't anywhere about, or I dare say there would have been words spoken to them, too. And one of them was a Post Office van, which really had no choice. It was parked as close as possible to the back way into the Post Office, and would be gone as soon as it was loaded up.

I mention the incident in some detail, not to single out the lady in question, but because she is so typical of the drivers who do park on the double yellow lines around Hay. She seemed to think they were optional, and didn't apply to her.
