A Starbucks barista in San Diego got screamed at by a woman when he wouldn’t serve her until she put a mask on.  She claims she has a medical exemption and can’t wear one.  But people are dragging her online, because she took a picture, called him a “sheep,” threatened to get him fired, and tried to shame him online.  A guy named Matt Cowen started a GoFundMe page for him that’s already raised over $27,000.
