Don’t look now, but that man who just walked into the store behind you is not here to shop. He’s a shopping anthropologist on assignment. His employer just landed a big contract with this store. They want to know what makes you tick, and why you do the things you do. Once they have this data, they'll use it to manipulate and control you to do their bidding and improve their profit margins.
He’s watching your every move, taking notes, timing each of your behaviors, and reporting back to central command.
