A Tesco shopper who popped into one of the supermarket's stores to buy his son a sandwich was refused entry because he hadn't downloaded an app.
Jonathan Rowson was told he could not enter the central London shop last Tuesday night unless he had downloaded the Tesco app and signed up for the Clubcard.
Jonathan, who was trying to buy his son a sandwich for his packed lunch, described the ordeal as "distressing" at the store in Holborn.
