I do know retail theft has skyrocketed the last 5 or so years.
Yeah the stores did that.
They knew self-checkout would be shoplifter heaven but they calculated that they saved more by cutting jobs. Then they cry for insurance and government payouts by pretending there is an epidemic of crime.
And now they're cutting back on the self-checkouts while not bothering to hire people back to work the registers lol. The lines are getting longer and longer.
