I don't use tesco as a point of principle, but supermarkets for years have been profiling people. If you have a loyalty type card, they analyse your purchasing habits to send you special offers and if you did not tick the opt out box, sell your data (and your purchasing habits) to third parties.

As has been said, they have been using CCTV for knocking on decades and they have had the chance all along to link your image to what you buy, more so in the last 10 years or more of digital imaging.

Unless you buy everything from small shops and only pay cash, the trail exists and there is nothing that can be done.

As it is, the data stored on people at the moment by such organisations is benign; they analyse the stuff you buy to try and sell you other stuff. It may be, that in the near future, it is used for more nefarious purposes - to exert undue influence upon you or profile you as not conforming to type.

Case in point is Amazon. Look up a certain item and be told what other people bought with it.

"Hmn, wonder what could be put together with those items"
