Like a job or a game?
I have several times:

In a practice quiz game people where buzzing in before the question went up. I walked out.

When someone used a cheat code in a Street Fighter arcade I walked out.

I walked out when my Christmas holiday was given away to a new employee.

I walked out of a baseball game when I wasn’t allowed to read the rules and I was struck out when after the fact the umpire thought that I bunted on a second strike? I took my left-handed mitt and walked to my dad and told him that I quit and we went home.

I walked out in special ed on the first day when I asked to learn calculus and they said no. I was told to spin for fun. I walked back to my desk in my old class and no one asked any questions of me.
