One time I had food poisoning, and my retail job would only let you call in sick 3 days in a row. After that you had to show up regardless of a doctors note.

On the fourth day of incessant vomiting, I tried calling in, and they said tough shit.

So, I drug myself into the car, drove up there walked up to my boss, grabbed a trash can, and threw up in it. She decided to let me go home.
