Thanks Everyone! I too received one of these PCN at Lizard Point, got held up in the cafe and went over the time. Some scruffy Git with a Cast on his leg had slapped a ticket on my car. He had been lurking around in completely inconspicuous Rover saloon car which they had some miniscule magnetic signage stuck on. I was really fed up as I must have spent approx £50 already on parking whilst on my hols. Anyway, After reading all of these posts... stuff em!! I'm going to sit back and let the threats come rolling in. Fingers crossed
