Your correspondent who was fined in a car park owned by a Tesco store for apparently not displaying a 'blue badge' should perhaps refer to the main branch of the one of the three Tesco stores in Dumfries, where at least 50% of the vehicles using disabled bays do not display any form of blue badge. I have written to the manager of this store twice in the last year and have received the usual avoidance spin that multinational companies use to disclaim responsibility. As a result of their lack of policing this store is now boycotted by many disabled customers.
