If you drive off while a parking warden is typing your details into his machine do you still get a ticket (through the post)? I parked at the end of a parking layby, off the road but there are double yellows on the end bit, and popped into a shop. Only two minutes but I was over the double yellows so fair cop I suppose.... Once I got in the car he put his machine in his pocket but I'm wondering if I will get a letter.
