Mike Dewine, the Republican governor of Ohio, spoke about this on Sunday. Masks should be mandated for all customers within retail stores. They aren't because of the public backlash.
I don't think you'll see an order in Louisiana for everyone to wear masks outside of their homes. That would never work. But an order for masks by customers within retail businesses could be coming soon, backlash and all.
At some point you're going to see retail store employees demand it.
