That's it. You've had it with the organization you work for. They've made you work too hard, they've grown corrupt, or they've done something morally questionable in pursuit of their goals. You're quitting, but you don't just want to turn in your Two Weeks Notice and walk off the job. You want to let your employers know just how disgusted you are with them. What better way to do that than by walking up to them, tearing off your chevrons, ranking insignias, and other badges of office and throwing said items into their faces? (If you've recently been awarded a Medal for Valor or for some other reason, feel free to rip that off and cast it dramatically to the floor as well. Your employers should get the message.)
