The self-checkout navigation is intentionally hobbled, probably because old people will 'press' a button about six times with shaking hands. Feels like they're putting button presses into a buffer for a half second or more. Watch next time an employee has to "help" you with self checkout: they scan their badge and then can press buttons as quickly as they like. I've noticed recent iterations of self-checkouts are much easier to use. Feels like they've relaxed the weight-on-tray requirements. And at self checkouts with the option of a handheld scanner, use it. Often the handheld scanner seems to bypass the place-item-in-bagging-area thing.
