I went out unmasked and so far 6 of 6 in not being confronted when going in. A few places have a small sheet of paper saying masks required, but many still unmasked and no stores seem to be enforcing or saying anything.

I imagine there are a few places that might say something (looking at you Wal-Mart) as they have build cattle runs where you have to thread your way in and they have people manning it, but Wal-mart sucks and I don't have to go there.
