“However, even the self-serve need attendants to help some of the customers, verify your age if you buy alcohol, etc.”

Correct. But they could be paid more than the average cashier. I am not against automation at all. They still have cashiers, mainly for the folks who don’t like self-serve. Because I was a bagboy in high school 40 years ago, I prefer self serve.
