Yesterday I parked in a Pay & Display car park. The ticket machine was out of order. Lots of other cars had written a note and left it on their windscreen - saying they had tried to pay but the machine was out of order. So I left a note in my car, stating the same.
Was away for about three hours. When I returned to the car, there was nothing to indicate that anyone had been round, checking for payment.
Did I commit an offence, leaving the car without paying? Should I have driven off to another car park? Am I likely to get a fine through the post?
