In the hope that my experience will inspire someone here - I haven't worn a mask in Walmart or Kroger for about three months. So far, no one has stopped me, said anything to me, or given me so much as a second look (that I'm aware of). And no, I am not intimidating-looking in the least. I keep an eye out for anyone else who is doing the same, and at most have seen 2 others who aren't wearing masks either. Often I don't see anyone else at all. it's discouraging, but I'm not going to give in.
