You ate my last chicken nugget, beat my high score, but worst of all, used the wrong preposition in A MEETING!
Your profile picture is a melon-colored crayon, instead of your face! That doesn't tell me anything about you!
Listen... I was the one who told my boss that you should be hired because I thought you had a lot of potential. Look, I trusted you. HOW DARE YOU BETRAY THAT TRUST BY BREAKING MY CRAYONS AND EATING THE LAST CHOCOLATE CHIP COOKIE! YOU ARE FIRED! GET OUT!
Contrariwise, this is Undercover Boss. I am the Boss and since you questioned my authority,YOU are fired. (Also because you seem to have no regard for chocolate chip cookies.)
Focusing too much on chocolate chip cookies and thus failing to bring a banana to the company party, bananas are cool, you're fired!
firing an employee because they do not share your liking of bananas? You're too biased and opinionated in the workplace, I'm afraid you'll have to be leaving us.
I can see through your veiled support for these anti-banana conspirators. You're fired. Security will escort you from the building...
