Bastard Parking Ticket

Parkign in Cambridge yesterday, I paid 1.50 to park for 45 mins.  Upon returning 10 mins late, i found a ticket on my windscreen.  The ticket said the warden had visitied the car at 1:11, and then returned at 1:21 to issue the ticket. The ticket expired at 1:12, and I returned at 1:24.

What a disgrace.  I normally cycle/walk, but was in a rush. Bastards!
