Unstaffed tills were supposed to revolutionise shopping.

They were?

Self-checkout systems are already old fashioned. Most stores in my town have apps for that now, where customers scan items as they bag them in their own bags while walking through the store and then just beep out. This removes the need for a queue, the payment terminal, the receipt and the stupid exit gate. Customers are allegedly randomly checked, but I've never seen that.

I hate self-checkout. It's just annoying and a downgrade from an actual. cashier. I'll use it when I have to. But really it's just terrible.

However, scan as you shop. That's just great. Put your bags in the trolley, scan and put it straight in the bag. Go to checkout machine, pay and your stuff is already bagged.
