I have just come back from a bit of shopping in Sainsbury's, Sloane Avenue. When I went to the self checkout, all of the screens over all the self checkouts started up with me and my young child recording us . We were on the screens of every self checkout, up close recording with bright red flashing light with RECORDING IN PROGRESS on it. I am utterly freaked. I have been going there for 19 years and I have never stolen a thing in my life. Surely, this is a serious GDPR breach? I videoed it as evidence. It's our local but I never want to go back into it .
