I was shopping recently in a supermarket when I kept spotting isolated products seemingly left in the wrong places.
It looked as if people had found product B afer having placed product A in their trolley and then dumped A in the wrong location.
Today’s invention is a simple way for supermarkets, which are always intensely data-hungry, to make use of this extra stream of information.
All the shelves in a supermarket would have a small trough running along the bottom.
If customers did an ad-hoc swap, they would be asked to put the reject item in the trough when they picked up item B.
This would allow staff to easily locate any produce requiring rehoming but it would also make them aware of when a strong preference has been expressed…vital for future marketing.
