I work at a fast food restaurant. Not sure if everyone knows, but to remove orders from the monitors after they're cooked/handed out, there's a keypad where you press buttons to remove them. Most of the time at work I'm the backbone. I have to back everyone up, and still do my job at the same time. Well, one night everyone was doing a shitty job and I messed up an order slightly. Well, I got pissed off because I was sick of all the shit and I punched the keypad hard. Next thing I know "Eric, we can't bump orders...". I go outside on my break after, and then the associate manager comes out "You broke this. You're in big trouble." She had to call the general manager, and then the owner of the store. And the owner was out at dinner with some people on business. Even though she didn't want to, she had to write me up. First and only time I've ever been written up.
Next day I find out the thing I broke would cost me $200 to replace, all from my pay. And I'd just got back from vacation, so I wasn't going to get shit for money. Turns out that it was under warranty (warranty for someone going apeshit?), and I only had to pay $25 shipping for a new one. So that was awesome.
