I have just received a parking ticket from a supermarket car park. I called in on Saturday morning and left within fifteen minutes, and then visited again later the same evening. In between these visits I went to Ely and had lunch using my credit card. They show pictures of my car arriving at 9.02 and leaving in the dark at 19.37. There are notices on display warning of penalties for overstaying the ninety-minute period. The paper sent to me is headed "Civil Parking Charge" and, in the terms and conditions, states that there is “reasonable cause to believe an offence has been committed”.
