It's not subtle. If there was an employee standing next to you or following you around the store with a clipboard taking notes on you and your facial expressions, only then would you have something approaching an apples to apples comparison. Stop pretending that's normally "what sellers and owners do" and you're just automating it. Customers Do Not Want.
