People wearing it below their nose may just be subtly resisting. When I go into a store that demands I mask up, my attitude is, you can make me put on a mask but I don't have to wear it properly. This way, they get their mask rule submission and I get my air to breath. I also notice the tide is changing slightly in my area. Some major grocery stores only ask politely to wear a mask and others have taken down any mask requirements completely.
