I parked up in a 20 minute drop off zone at the local hospital and managed to overstay by a few minutes. I Have attached a photo of the sign, no where does it stipulate that I can't return to the bay, so although I can see that they have two images over 30 minutes apart, how can they prove that it wasn't 2 separate instances i.e. I left and returned. Any advice will be much appreciated. Parking ticket issued by UKPC
Note: Sorry upload not working but sign states that "maximum stay 20 minutes" - no mention of not returning.
