California has a statewide mask order. I wonder if anyone has ever been fined for violating it?
According to CalMatters, Beverly Hills has issued at least 103 fines to an unspecified combination of individuals and businesses:
Beverly Hills has cited 103 individuals and businesses since the city’s fines took effect, city spokesman Keith Sterling said, but he could not provide information on the amount of money involved or whether there were repeat offenders.
According to the San Antonio Express-News, San Antonio has also issued many citations, including several that were clearly issued to individuals (emphasis added):
One employee had the mask sitting on his chin after receiving a warning. The business and employee were cited.
Two citations were issued, one to the the business for employees not wearing masks and one to the owner for not wearing a mask after a warning.
All of the employees corrected the issue immediately, except for an American Cookie Factory employee who was not willing to wear a mask correctly. The employee was cited along with the three store owners.
As far as I can tell, it's up to local enforcement agencies to enforce the mask order, so cities issuing fines (possibly under their own laws implementing the order) would seem to be the primary way that fines would be issued for such violations.
