I left my mobility carrying van in a disabled space which has mobility stickers all over it with my blue badge on the sloping dashboard but it must have slipped off because it was on the floor when I returned .so I got a parking charge £70 or £30 if paid promptly ,so I paid it . All Tesco could say was go through the appeals process but added if you paid you could not appeal .Not Happy User's recommendation: Stick your badge on with super glue or shop elsewhere.
