My local Target had also done this most of the past year but re-opened them recently, thankfully.

That's really surprising. In my experience its so much faster than traditional cashier.

They're not effective at reducing/preventing shrink. Unsure what the time situation is at scale for the stores. To be sure I'm faster and better at bagging but holy crap some people are not.

Shrink meaning theft? That would make more sense to me.

Interesting, I rarely go to Walmart if I can avoid it, but I've noticed the stores here seem to only have a couple staffed checkouts left. There's 14+ isles of self checkouts.

Depends on the neighborhood
