Hello, hopefully I've included all the relevant information.
The driver parked in a bay marked "Budgens customers only" between the times 16:26:11 and left 16:33:53 (shown on the PCN). During this time the driver said they think they checked their bank balance at the ATM which is attached to the shop/petrol station but can't remember if it was on a different day, they entered the nearby fish and chip shop briefly, then got in the car and left.
My dad is the registered keeper of the vehicle. I'm getting advice on his behalf.
I was under the impression there was a grace period of 10 minutes that a driver could potentially observe the signage and choose to leave or not, I'm not sure about that though.
Thanks for taking the time to respond. I'm struggling to get the files to upload so I've uploaded them to Imgur
