Empty Candy Dish Sends Young Associate on Downward Spiral

My assistant has a candy dish. She keeps it out in the open so that anyone can get at it, which I suppose is fine SO LONG AS she is there to replace whatever they take so that there is more for me ME! when I need it. But it should be OBVIOUS TO EVERYONE that since she is MY assistant, I get DIBS on the last kit kat after hours. This is simple etiquette! Who are these barbarians??? They all have their own assistants who chose, for whatever selfish reasons, not to provide a candy dish for them. That is NOT MY PROBLEM.
