It's an interesting question
Theoritically if the spoilage numbers (what they lose from people cheating the system as suggested) is higher than the cost of of paying the cashiers than the should go back to cashiers. So why haven't they?
It's an economic concept known as "sunk costs". If they go back to humans, all the money invested in machines is lost. If they keep tinkering with the system, it protects their egos.
Yes, but going forward the accountant at the stores, especially the big ones would say to dump the checkout machines and go with the cashiers again. Even Wal-Mart who was a late adopter would stop using the checkout machines.

Yes, the underlying assumption is that humans are rational is blatantly false.Quite. I read The Economist every week, and, as far as I can make out, these 'laws' cover the only the doings of rational and total selfish beings such as may exist on Mars but are lacking here. Mostly they mean quite simply, 'we back the rich!'
What's the definitional of rational that you are using?
