I would say at least 1 time in 5 I encounter some kind of issue with the self-service checkout at my local supermarket. The scale won't work, or it doesn't detect when I've put something in the bagging area, or a barcode isn't recognised, or something else. And that's leaving aside the times I try to buy alcohol (or NA beer...) and need approval.

And then I have to stand there like a twat for 20 minutes trying to get the attention of a member of staff because there is one staff member for 20+ machines and everyone is having the same issues.

The technology may or may not have delivered for shareholders, but in my experience it hasn't delivered value for customers. Perhaps the bigger question is why we put up with stuff like this.

Maybe it'll get better in time (though it has had many years to improve already). I used to despise the passport machines in the airport, now I merely dislike them.
