This one woman I used to work with didn't just burn bridges, she nuked them from orbit. We were contractors on a military base. She was in configuration management. She was in a meeting with a bunch of the division managers, it was a stressful day.

In the middle of the meeting, she blurts out, "Fuck this. I don't need this shit."

She gets up, leaves the meeting, and walks back to her desk. She drops her stuff in a box, walks out of the building, and drops her base pass off at the main gate.

Nobody heard from her again.
