What is the worst thing you could say to someone who's been fired?
It's difficult to say, as I cannot know the whole situation to find the worse thing, however a pretty bad thing to say to someone who's been fired is: "What are you looking at? Get your things and get out of my face!".
It's important to note this is only relevant to say right after firing that person.
