In some places I have come across you can pay for your parking by phone, well it seems even if you are parked up but the engine is not switched off you can be breaking the law. Lincoln City Council do not put that on the notices. It came to my attention as a customer of mine got nicked last week in a Macdonalds. Must admit although I certainly do not use the phone when driving I would not think to turn the engine off prior to paying for the car park.
