By making Mask wearing obligatory for employees (grocery stores…) have "governors" increased the risks for these employees? Should they be held accountable for that?

If you live in a state w Mask Rules, ask grocery store employees how they feel about the rules. Look at how well their masks do (or do not) fit.

"If it's not fitted right, you're going to fumble with it," explained Health and Human Services Secretary Alex Azar before a House Appropriations subcommittee on Wednesday. "You're going to be touching your face, which is the No. 1 way you're going to get disease, is unclean hands touching your face."

Surgeon General Jerome Adams: "You can increase your risk of getting it by wearing a mask if you are not a health care provider," Adams said. "Folks who don't know how to wear them properly tend to touch their faces a lot and actually can increase the spread of coronavirus," he added.

Amesh A. Adalja, MD, senior scholar at the Johns Hopkins Center for Health Security: “There is no situation in which a face mask might provide increased protection to the general public, even during air travel, says Dr. Adalja.”

Do the grocery store employees have: Masks that fit? Masks that are approved to stop Corona? Or just masks that are wet from breathing?

If a person lived in a state with Mask Rules yet refused to wear a mask in stores, they might be surprised at how happily they were greeted. Not everyone likes Big Brother thinking he's in charge. (Not that I would ever suggest rule-breaking).

In closing, I'll take care of something for other Anons; “You wrote so much text.”
