I'm in Australia but similar sounding system is in operation at our two major supermarkets.

I scanned a drink, heard the beep, put it in the bag. I scanned a loaf of bread, heard a beep, put it in the bag.

Now, instead of the typical "Unexpected item in the bagging area" it now shows the overhead replay and locks the system out until an employee comes over to review.

Combined with their exit gates that don't open if they think you've not paid for something, and cameras that track you through the store it's feeling very unfriendly.
