More than $21K in tips are donated to a Starbucks barista after a 'San Diego Karen' tried to shame him in a viral Facebook post for refusing to serve her when she wasn't wearing a mask (7 Pics)

A fundraiser offering tips to a California Starbucks barista has raised more than $20,000 after a woman attempted to shame him for not allowing her inside without wearing a mask. 

Amber Lynn Gilles, a yoga instructor and photographer, took to Facebook on June 22 to blast the barista - identified in the GoFundMe fundraiser as Lenin Gutierrez - for not serving her at a Starbucks in San Diego. 

'Meet Lenen from Starbucks who refused to serve me cause I'm not wearing a mask,' she said in the post, tagging the coffee shop off the 4200 block of Genesee Avenue.

The now viral post has been shared more than 47,000 times and has been inundated with comments from people slamming the woman for her post. 

Under California Governor Gavin Newsom's mandate regarding mask, people can be exempt for wearing masks but must provide a medical reason.

The post prompted Matt Cowan to establish the GoFundMe for Gutierrez, who he did not know. The two have been in communication and have plans to meet up, with the barista sending Cowan multiple videos and posts where he thanked his supporters.
