Dr. Marc Siegel reports on a new hope in the fight against coronavirus. A fed-up Denny’s employee quit her job after customers challenged the restaurant's current mask-wearing requirement during the COVID pandemic. A Denny’s server at the restaurant chain's location in Franklin Park, Ill., can be seen announcing her intentions to quit in a cellphone video posted to Reddit on Tuesday after customers refused to wear masks while citing the "Civil Rights Act of 1964." WARNING: Video contains profanity. The customers in question do not comply, claiming "religious exemption." "You know what, you know what? I quit, I f----ing quit," the server says.
