If you find a mask non-compliant open to debate, here's a blurb for them:
When a surgeon wears a mask, he or she is not preventing 100 percent of pathogens in the wound, but reducing that potential pathogen load significantly. Numerous other measures are taken to help prevent wound infections.
The alveolar relative surface area of our lungs is approximately equal to a football field if flattened out. That's a lot of exposure area of the thinnest tissue in any animal's body between the bloodstream and the air. Surfactant action and trapping of pathogens and other undesirable particles by the thin layer of phlegm gets seriously compromised in unhealthy individuals, rendering much of that exposure area akin to an open wound.
Now, if the surgeon getting ready to work on you were to say "I won't wear a mask during your operation"....
You'd kick that dumb butt right out of your life and go find a competent surgeon wouldn't you?
Similarly, if anyone in the surgical suite is maskless, they are adding to the pathogen concentration in the air, the further away the lesser among droplet type vectored pathogens, but spreading a significant number of airborne. Exactly why no unmasked, unclean person is allowed in.
So, extend the concept. The smaller the enclosed area, the more flora exchange between occupants, depending on air circulation.
Outdoors, for the most part, is relatively safe to go maskless.

A young lady asked me if the store had lox. I told her she'd have to go to a hardware store. That was a long time ago, I'm sure grocery stores now carry locks and lox.

and that is considered, an assault, if I am not mistaken.

No, you can't make this stuff up..?

some kind of assault or intent to cause harm. I just did some googling and this came up: Aggravated Battery...

Aggravated Battery:

The Battery and Injury
The specific intent in the aggravated charge may also happen by depriving the victim of the basic rights a human should have. In battery, this may exist in the basic right of freedom during the injury. Other specific intent involves the purposeful activity of causing harm with the very intent to ensure that the person injured will continue to suffer. Having the purpose of maiming, disfiguring or causing serious bodily harm is the specific intent crime of aggravated battery. The aggravated may also involve the deadly weapon use during the crime or discharging a firearm with the intent to put the victim in the hospital or in an attempt to render him or her unconscious for the long-term such as in a coma. (hg.org Legal Resources)

I don't know if the above description would apply but it seems like, as I mentioned above, the intent to cause harm would apply (I'm not an attorney so I don't know.).

If there is a law, I think this person should be made an example of....truly disgusting...
