This should make you smile, I was away from the firms vehicle for less than two minutes, I wasn't illegally parked, but the r'sole of a traffic warden seemed to think I was,
No yellow lines no restrictions.. besides I thought they had to give you about 10 mins, ie they had to observe you twice, hence the 20 min difference on your notice.
After I looked closely at the ticket, the guy was in such a rush to write it, he got the reg. number slightly wrong.

I saw I him "down the road" and said, I've broken no laws, I'd see you in court, except, you were in such a hurry to write that, you f***ed up.. Have a nice day.
( Of course I didn't tell him how, and that was the last I heard of it )
