You forgot to include a lawsuit filed when someone scratches their face while putting the mask on and then developing a dreadful infection.
Or the suit brought forth when the mask wearer sneezes and near about drowns in their mucus filled snot.
Heck, lawsuits can be brought on for anything and everything.
Lawsuits against all businesses, religious halls, government at all levels from local station to federal and even foreign, against employees and employers, against customers, co-workers...
But none of those silly class-action suits. Individual suits will rake in the big bucks to help rejuvenate the economy by increasing spending dollars for everyone. Even lawyers who can file suits against each other!
