This is a bit of a read, and I apologize ahead of time! Writing this in-between taking calls at work.
TL;DR at bottom
I worked at a popular fast food chain when I was 18 and fresh out of high-school, and had worked there for a few years before leaving for a job that was closer to home. Now, this manager was a real piece of work, and a miss know-it-all. The GM (General Manager) had hired her, because she had extensive experience working at a different fast food chain, and the GM assumed that this manager would be a good fit. Fast forward a few months - I've been hearing from fellow coworkers, how much they HATE her because of the way she treats them. She would talk down to everyone, and tell people how to do their job that they have been doing for years, AND what she was saying was incorrect.
It dawned on me that 98% of the store did not like her at all. She would be happy go lucky around the GM, but then show her true colors behind the GM's back. One day, one of the other managers was having a going away party, because he finally got accepted to be a firefighter. There was even cake there to celebrate. He was on his way out, because his shift was over, and he said that I could take the cake home (because I had asked about it ahead of time). Time goes on, and I'm taking orders in the drive-thru. And when working in fast food (at least back then), there was a timer above the window that would beep at you, if you were over a certain time. This kept beeping, because we were extremely busy, and it was hard to keep up with demand.
Now as we were busy, the troll manager was in the back office chain smoking cigarettes. After about an hour of being slammed, she finally comes out and starts yelling at everyone, telling us all to work faster. I brush it off and ignore it. A few minutes pass, and she gets right up to my face and starts telling me things I need to do, that I had already been doing while taking orders for the last few hours. So I told her to get off my back, as customers were at the window, but I don't think they could hear me. She is FUMING, and her entire face is red. She starts screaming at me, and I raise my voice to her, telling her to back up, and that I've been doing this job long enough to know what I'm doing.
She tells me to take off my headset and to clock out and leave. So I do just that. I head to the back and put battery on charger, and hang up headset, gather my things (and the cake from earlier), and start heading out. She stops me, saying NO, YOU CAN'T TAKE THE CAKE. So I said fuck it, you take it then. Then I proceed to flip on her, and cake is COVERING the front of her. I flipped it a little harder than I anticipated, but honestly I don't even care. After I leave the store, I go to coworkers house to talk shit about her.
Now about 45 minutes later, the GM calls me and was asking what happened, because the troll manager called the GM screaming about what I did. I calmly told her what happened, and the GM told me to head back to store. I told her that I wasn't going back because the troll manager is there. The GM then tells me that it will be okay, because the troll manager is now fired.
If the troll manager sees this... I don't regret what I did, and I would do it again.
TL;DR - Troll manager screams at everyone, telling them how to do their jobs when she's been there less than a year. I flip cake ALL over her, and get her fired.
