As the customer you're already taking stuff out of your cart and putting it on the counter. Maybe automation isn't the right word, but it's certainly more efficient than having a human clerk. It removes a bottleneck.
But it’s not a bottleneck. It’s the opposite. An experienced human checker will tap in the code for oranges way before you find it in their stupid menu.
It is a bottleneck, because the experienced human checker is only entering orange codes for one person at a time. There could be ten people all checking themselves out simultaneously. Even if one or two get slowed down by a menu, it's still a net decrease in average time spent at checkout.
And introduces others: “unexpected item in bagging area”
True, but isn't that an implementation issue that can be fixed, rather than an inherent issue with the concept?
