I’m not following. The barrier separated the cashiers who were mandated to wear masks from the customers who were asked to wear masks (asked vs absolutely forced after violent protests by angry “freedom loving” customers). It was essentially like a giant plastic face mask that medical staff were wearing at the time in addition to masks. I’d sure like it to be present in the same way I wouldn’t eat at a buffet without a sneeze guard. You’d fault the company for spending time and money building those out for their cashiers? Keeping the store open - while asking everyone to social distance and wear masks - kept people employed and allowed mothers that needed to stop by a store to pickup something when they may not have another option to do so.
