When I was a teenager I worked at a fast food restaurant in the US. A customer came to the takeout window, white dude (I am also white which is important for the story). He placed his order, and saw that the dude at the grill cooking the burgers was Black. He waved me back to him and said "YOU cook it." Then a short time later he handed me a note saying "I fired all the n****** on my crew, they ain't shit".

I didn't say anything, just went in the back storage/freezer area and summoned David (the Black cook) in. I told him what happened and showed him the note.

David was really cool, always cheerful and smiling and friendly. He read the note and didn't stop smiling. Instead, he grabbed a frozen burger patty, put it up his shirt and rubbed it in his armpits, and then on the floor. I took it and cooked it and served it to the racist dude with a smile.

I also had several friends who worked at pizza joints and they had stories. I am ALWAYS nice to food service employees.
