Did we ever get to the bottom of the discussion about why shops needed to scan boarding passes when buying things? Just bought some Skittles at LCY and when asked for my boarding card I asked why?

They replied 'company policy' so I asked what they were going to do with the data, to which they said "we don't use it" so I said no then. They still sold be the Skittles!

Is it just a mindless response or am I missing something? If it was about them pocketing VAT surely they should say so?

Cheers
