Break her heart

You smile coldly at her.

"You won't get better. You're fired," you tell her horrified face as you gesture to the door. "Get the fuck out of my office."

"But....but....but if I gave you my ass you'd let me stay!" she wails. "You said..."

"No, you said. I didn't say any such thing. Besides, you didn't give me your ass, I took it after your tried to back out of the deal. That's the absolute final straw. Get out, or I'll throw you out."

"Please sir, please! Grandfather said I could have eight days to improve, and I want to please you, I really do, please give me a chance, please sir!" She falls to her knees, holding her hands out to implore your, her face crumpled with grief and stained with tears.

Mercilessly you pull her to her feet by her hair. Sneering, you put your face close to hers as you speak.

"You're fired. Get out. Go on your own or I will call security and say I caught you stealing. I will ensure that you never get another secretary job in the city again. You have ten seconds to choose."
