A woman who became irate and started yelling at a Starbucks barista as he tried to explain Starbucks’ face mask policy to her posted a video of the exchange on Facebook. The post, which received more than 110,000 likes, also ignited a wave of support for the barista, Lenin Gutierrez, in the form of an online fundraiser that has raised more than $87,000 to date. Mr. Guitierezz intends to use the money to pursue his dream of teaching dance.
