As manager Damien Corcoran explained the check-out system to her (because, let’s face it, the Queen has probably never set foot in a supermarket before) she couldn’t resist asking: "And you can't trick it? You can't cheat then?"
To which Mr Corcoran patiently replied: "Well, you always can cheat but with the weighing scales we've got that should prevent certain items from being undetected."
During her time touring the store, the Queen was also shown a new shopping app, which she called “an interesting tool” and reflected on her own experiences of wartime rationing.
“As a Sunday treat we had some sweeties, but we were lucky we had a farm.”
