Mandatory mask-wearing is decided at the local-level (county or city) in the state of Alabama. In Jefferson County where I am it became mandatory on Monday of this week. Yesterday I forgot to put it on when I went into the Walmart but already had a few items in my cart with just a couple to go. I felt like a criminal until I noticed a few more people without masks, but no more than 5% scofflaws like myself for sure. But having lived with the anxiety I doubt I'll ever forget it again!
