What's the worst "Bonus" a job has ever given you?

At some point I was doing the job of 4 people and teaching a new one, due to several maternity leaves. My boss calls me in a meeting room snd starts telling me how she appreciates my effort and she wanted to give me a one time bonus. She was very proud of herself for that. The bonus was a one time payment that would be enough just to buy a large pizza! And she insisted I hide the content of the information paper so that the colleagues don’t see it. I soon searched for another position in another team, seeing how much she appreciated me. I would have been less offended if she would just acknowledge my work and don’t insult me with that bonus.
