Heh. I know that idiot, at least one of them. Personally. At least for some of the major retailers that are making the switch who have very small bagging areas.
It's not his fault, it really isn't.
He got a list of requirements. Table is so big, scale is so big, computer is so big, and so many checkouts in so much area.
Every component has a minimum size requirement, and when the client isn't willing to bend on how many check outs must fit, the only other option is to shrink the one thing that can, and that's the bagging area.
Then they pile a bunch of shit in the bagging area, they have these giant caddies to hold thousands of bags, and they put three of them up there.
My understanding is that it's about loss prevention.
They think that self checkout is a high risk for shoplifting, so they want it to be a manageable amount. They need confidence in their security monitoring strategy before they go all in.
After a long trial here including employees monitoring and AI monitored video, the store near me now has maybe 30 self checkouts, with 10 having nice big bagging areas. I never have to wait in line anymore.
