Walmart has extremely good facial recognition software, which I assume now has been taken over by AI.
I also get my reusable bags checked at Walmart (I rarely shop there anymore),they will even make me take out all the empty ones in my larger bag to prove I'm not stealing. I figured it was strore policy.
I do know retail theft has skyrocketed the last 5 or so years. I have read stores getting rid of self checkouts because of this.
