It's also increasingly appearing to be the case that checking out yourself is adverse selection.

People with money have others shop for them, or ship to their house. The checkouts are for those who labor in that system who must now submit to the panopticon.

Security guards, motion-activated cameras that play sounds and nag you to remind you you're surveilled, manned turnstiles to stop door crashes with loaded carts -- all these adversarial controls suggest you're now in the wrong customer channel.
