How does Char act toward the lunch ladies, and what happens as a result of her behavior?

One day in the cafeteria, Char finds something unpleasant on her burger. No one's quite sure what it is, but it kind of looks like something that used to be alive. Char's already been loudly complaining that the burgers look like "burnt dog doo-doo," but the discovery of the yucky substance—whatever it is—is the last straw. So she gets her little lackey, Maleeka, to take the food back. The lunch lady, Miss Brown, tells Maleeka that she'll only accept it from Char herself. However, she soon changes her mind and starts throwing the food into the garbage. But Maleeka stops her, and takes the burger back. In a surprising act of rebellion, she scrapes the yucky substance off the top of the bun and smears it all over the burger before covering it up with ketchup and mustard and giving it back to the unsuspecting Char.
