Reversing into a parking spot in ASDA, got half way in when suddenly reversing sensors started going berserk, slammed the brakes on, still couldn’t see any obstruction through the back window, I got out to have a look & there was a fat dickhead on. Small mobilty scooter, he’d come off the pavement to try to beat me, he glared at me & had the cheek to tell me to fuck off, I think he was actually after a claim but was pissed off as his plan didn’t work, normally the mobility scooters park obstructing the doors, I told him if he didn’t move it he would be walking home as his scooter would be on ASDA roof.
