I think it's a generation thing. Two of my kids use them every shop, personally I detest them but I'm an OAP and would rather deal with a person.
Local small ASDA has now only one manned checkout and its never manned. I only pop in for odds and ends but last time it would not accept an item. Along came a young man to help, it wouldn't work for him so he did something and gave the goods to me for free. Next and last item cat food, wouldn't scan so again got foc. He then closed the thing off saying it was broken. I asked why the only proper check out was never in use and he said the queue gets too long !!!
