A couple of years ago I was working for a contractor serving Tesco. I turned up at a branch, parked, went to the security office and signed in with my name, car registration and employer details, did a day's work then signed out again and left. 10 days later I got a letter from Parking Eye accusing me of outstaying my welcome as a shopper and threatening a hefty penalty if I did it again.

Not wishing to sour the relationship between my employer and Tesco I did not complain, but I did write to then minister in charge of the DVLA to ask why my home address had been disclosed to Parking Eye when I was lawfully on the premises. The minister replied that all applications for private personal information were assessed on their merits before the information was released.
