NEW YORK/PALO ALTO, U.S. -- Krystal Ji, a China-born lawyer working in San Francisco's busy Financial District, believes that wearing face masks reduces her risk of contracting the new coronavirus. But a seemingly minor incident last week convinced the 26-year-old to ditch them.
Ji was waiting for the elevator in her company's lobby, wearing a mask. When the elevator came, a man behind her saw the mask and decided to wait for the next one, even though there was plenty of room.
