They do indeed often have zero ordinary cashiers.

... except at the "PRO" checkouts. Which are actually just ordinary check-out lanes. Anybody can go through them. The signs mean nothing whatsoever.

I never go through their self-checkouts unless I've only got one or two pre-packaged items. I usually park on the "PRO" side, enter through those doors, check out on that side, and leave through those doors.
