Laine, who sometimes has anger issues, is having a dinner date with Kit at a local diner and Laine's chicken is under-cooked.
Laine wants to let the server know something's wrong with the food.
Laine calls the server over and calmly tells her that the chicken is still pink in the middle.
Laine calls the server over and begins to aggressively berate her for the horrible meal.
Kit is proud of Laine for handling the problem so well, and because of that, Laine is proud of herself.
Kit is embarrassed by Laine's behavior and walks out, so now Laine feels foolish.
