Only sick people should wear face masks to prevent coughing and sneezing into the air and onto other people. But not all sick people will wear face masks. Sometimes they don’t own a face mask. Sometimes they don’t think they are sick enough to warrant wasting a face mask on themselves. Somebody said, “I’m out of work. If I don’t make 23 cents a day, how can I spend 23 cents on a face mask?”
