In what world is "knowing how much you spent" not a reasonable design requirement for a supermarket?

Just to pick one user story, it's a lot harder to check / challenge an itemized receipt if you receive it hours later, once you're already packed things away or eaten some of them.

It is reasonable. The price is on the shelf. But if you insist they have this too: https://static2.srcdn.com/wordpress/wp-content/uploads/2020/...

It's easier to challenge an Amazon Go receipt than any other store. I just click the link in the email and get my money. At other stores, I have to go inside and wait in line behind other people at the customer service desk. I prefer to get on with my day rather than argue over the price of a cabbage.

You're looking at it backwards. Why would you ever want customers to see their total spend?
