This is what happens when your order the "floor burger."

This video, appropriately titled "Nasty ass Checkers," depicts a line cook in Checkers throwing a hamburger bun on the floor and rubbing it on the tiles to really get the dirt on the bread before picking it back up. Then she assembles the sandwich. Here's what could be going on:

a. The sandwich is either for her boss who gives her an unbearable schedule, or the owner of the Checkers franchise who pays her an unlivable wage.

b. The sandwich was in fact for a customer, and the woman in the video hates her job and wants to be fired.
