Went to Walmart today, for the first time in over three months. Masks are supposedly mandatory in this state. Walmart was limiting occupancy -- they had a gatekeeper, and there was a queue outside with Xs marked on the pavement every six feet. People in the line were generally pretty well-behaved, and the line moved quickly.
Inside, all store personnel wore masks. I would estimate that between a quarter and a third of the customers either didn't have a mask, or wore it down at their chin or around their neck/throat.
