We have now been told to wear face masks in public. Have even been shown how to fold a T-shirt and use rubber bands to make one. That this keeps us all safer since you can have the virus and not know it yet. That you are shedding the virus at that point.
One of the most vulnerable locations is the grocery store. From the cashiers to the stock delivery people, I did not see even one with a face covering that was not a shopper.
Any business still open should have masks on to protect themselves and the public as best they can.
