I have no idea if Tesco do that, as my wife discontinued online shopping with them due to too many unwanted substitutions.
However, when I was “doing the Knowledge” years ago, to gain my London Black Cab licence, I’d do a couple of days per week on an HGV driver agency, to supplement my income.
One of the jobs that I did often, was taking Tesco produce to stores in Suffolk and Norfolk in a 40’ refrigerated trailer.
During a delivery in Thetford, Norfolk one day, a guy hauled a pallet truck from the store to the loading dock, and threw a lot of food into a skip, one of the items was a box of four iced cakes.
I reached over and took the box from the skip, it had a sell by date on it, which was that day.
I said to the warehouse foreman, “I’ll have these, save throwing them away”, he said “If you take them, we’ll call the police.”
I said, “You’re kidding, surely?”
He said, “No, Tesco are terrified that if we gave the stuff away, and someone got sick after eating it, they’d be sued.”
