I was surprised yesterday. I'd say about 30% or more of the employees were not wearing masks. My daughter knows a couple people that work there, and they said it's not mandatory for fully vaccinated employees. My son works at WalMart, and employees are still required to wear masks for now.
I think we'll start to see more and more places drop the mask mandates, even though no one is checking to see if people are vaccinated. With close to 50% of the 16+ population fully vaccinated, I would think that the majority (more than half) of folks without masks are vaccinated.
