Yes it is, they babysit the checkouts and step in when needed. Their role is very much different than the role of manning a single non self-checkout. And let's not get into how the roles of the 9 other clerks have changed who are no longer there (spoiler: doing no work there and not getting paid at all).
If you thing self-checkout reduces clerk work by a factor of 10 you have not worked in low margin high throughput retail. Anyway, from experience i can tell you it’s a gradual affair.
