I worked at a bbq joint from 14 years old - 18 years old. The boss was a total bitch (threw water in my face, searched my car, made every day a living hell for me for no reason at all) so naturally when I quit I went out with a bang.
I just left in the middle of my shift (when I knew I had another job secured). I came back a week later to get my paycheck and she wrote a nasty note on the envelope that said something like "Thanks for being an asshole. Have fun at your other job."
Naturally I came in the next day and handed her a note back. I told her that she was the biggest bitch I've ever met as a person and worker. Then I told her to go fuck herself with the biggest shit eating grin on my face.
I'd do it again in a heart beat. They don't call me little lion man for nothin
