My parents (who are 70 and 71) have their mindset too. I disagree with that "I don't work here" argument - who said scanning items HAS to be something that only a cashier does? Why is it considered work compared to something like choosing and weighing vegetables, which is something no one ever expects a worker to do for them nowadays?

For me, the merit of those self checkout stations is that you can do this easy thing (scanning items) yourself. I don't need someone to scan items for me. It was the only thing that I still wasn't allowed to do by myself, and I'm glad it eliminated having to interact with cashiers. All I need the place to do is stock up items and make sure the place is clean.
