Twice
Once for showing up late to my shift at a movie theater, then them getting mad because I didn't go home right away after they sent me home (chilled with my friend outside of the theaters before our ride came)
And another time because I wasn't working "With enthusiasm" as a stockboy for a grocery store, but it was bullshyt. I worked early as fukk in the morning, in the cold, by myself, and after the overnight pay stopped so they made sure to fukk me. To top it all off, I had to listen to this depressing ass country music shyt all day in that redneck hick town grocery store.
Dude told me to finish out the day and go home, and I told him "fukk you" and walked home.
I was young both times though, and it was definitely on some racist shyt I don't think it's a coincidence when all your minority employees are gradually let go or fired, then replaced by blonde haired, blue eyed suburban kids.
