I agree about customer service being important Cambia. For real customer service, there should be a choice.
Your point about
They are difficult for older people and people with children with them
is only true for those in that situation who find them difficult.
You will have read that people on GN have mixed views about liking or disliking either sort of checkout.
Again, there should be a choice, or would all the manned till supporters deny that right of choice to others?
NB Watching in the Sainsbury’s next to a local primary school at home-time, I see most parents (with children) head for the self service checkouts, rather than standing in the queue at the serviced tills.
You say
They never work, exaggeration
you can’t pack as you go People do. They pass the item over the scanner and place it in one of the bags they have put on the other side.
and aren’t any quicker in the long run.
IYO, not in mine, or those who prefer to use them.
There should be a choice, especially in the bigger supermarkets.
Booths, being relatively small and expensive , can afford to just have manned tills, though even they (if you read my post above) have self service in some stores that get really busy.
