"F**k Black Lives Matter!" the lady yells as she walks out the door.

What is the world coming to? Regardless of one's personal beliefs about COVID-19 or the imposed mask requirements, there's no excuse to treat someone the way this woman treated a Starbucks barista in a San Diego suburb on Sunday. 

The barista, identified as Alex Beckom, 19, asked the customer to pull her mask up, since she wearing it below her chin. The cell phone recording, taken by customer John Glaude, does not show the beginning of the incident, but it captures plenty of Karen-ish behavior in the aftermath, concluding with a dramatic:

"This is America and I don't have to do what you say! Trump 2020! F**k you! F**k Black Lives Matter!"

Yeahhhhh. You can watch the footage here: 

The customer has not been identified. 

Kudos to Alex for the way she handled this nasty situation! Such poise and calm!
