We had a recent experience with one.<p>We had 3 or 4 bags we brought. We pressed "use our bags", pressed 4, and starting setting them up in the weight-sensitive area. By the time I finished setting up the first bag, the screen had gone back to the initial state, and when I set a bag down, it began complaining. It took a couple minutes just to get bags set up. We also didn't have room in the weight area and had to put some bags on the non-weight area.<p>Then we had quite a few issues with it complaining about moving or not moving things to the bagging area, several of which required waiting a minute for an employee to come over, type in their override code and clear the error.<p>Then we selected the wrong fruit because it wasn't accepting the 4 digit code, but it was more expensive, so we once again had to wait for an employee to come fix the issue, as you can't undo any mistakes on your own.<p>Overall the experience took 10-15 minutes (felt like eternity) and that compares to what would be 60-90 seconds with a cashier. Most of that time was waiting 30-60 seconds during each of the 4-5 times an error came up that we had no power to clear ourselves.<p>Of course one of the takeaways here is... don't use self-checkout for more than about 5 items max. One bag. Any more and just **ing go to a human. The other is... these systems are shit and they are not designed to work with your customers, but rather to use your customers, regardless of the toll it takes on them.
