Smart and Final also told me I had to wear one HOWEVER I don’t need to shop at Smart and Final so I left!! I buy my meat at Costco OR I would have left there also!! Walmart does not require masks so I go there early AM so I don’t have to deal with the screaming babies ect.
I live in a state where masks are required unless you have a medical reason. One chain grocer requires them and has someone at the door, another chain just has a sign posted and leave it at that.
