LATELY, we have read about/heard numerous complaints about supermarkets denying entry to customers who aren’t wearing masks. This is a wise move by the managements of supermarkets, as the latest recommendations by the US Centers for Disease Control is that people should wear masks in public, especially where social distancing is not possible.
