A former Carvel manager says refusing to serve a customer without a mask got him fired.

Thomas DeSarle says a customer was coughing into his hand when he entered the Glen Cove store last weekend.        

DeSarle tells News 12 he offered the man a mask, but the man declined before trying to pay with a wet bill.

That's when the former manager says he spoke to his boss who allegedly responded angrily. Two days later, he was fired.

DeSarle's lawyer says they may file a complaint to the state or even a lawsuit.
