I’ve driven through Oregon before back when you weren’t allowed to pump your own gas and it felt ridiculous and inconvenient waiting for an employee to come pump gas for you. But maybe that’s just because I’m accustomed to self serve.

For groceries it’s nice to have the option to do self checkout. If I have a small number of items then self checkout is faster/easier. If I have a large number of items then going through the line with the cashier is faster/easier.
