In Costco’s mask policy that has been in place since May, people with medical conditions that prevented them from wearing a mask were exempt. But now, Costco says if that’s the case, that shopper will have to wear a face shield.

“This updated policy may seem inconvenient to some, however we believe the added safety is worth any inconvenience. Our goal is to continue to provide a safe shopping environment for our members and guests, and to provide a safe work environment for our employees,” the letter to members reads.
