When you go through regular checkouts, you often aren't paying attention to the prices. You might be chatting with a friend, texting, or just otherwise oblivious. Scanning items yourself forces you to see the prices and you are more likely to catch errors. While some people take the view that they won't use self-checkout because it puts people out of work (or because they don't see why they should do the task themselves), this is a good argument in its favour.
