I think I'm going to leave a post-it on my 77 year old co-workers pc in his cubicle telling him his loud burps are disgusting and can be heard across the aisle. My other coworker took the blame and got in trouble.
Why would your other coworker end up getting the blame?
He was just unlucky and well he took the blame for me.
While your old coworker is indeed gross for doing such things in public, you are no better by leaving such aggressive notes to him. You embarrass him further and you could have accomplished things better by just speaking face to face.
You tell me that I should have known the consequences and I'm all OK with it. I mean he deserves it. Why do I need to get authorization, he doesn't and it's his own decision to burp loudly.
I am only speaking from experience because I was in your shoes before and I did what you did by leaving a note and it just went bad so fast. I don't want to see you end up like me, so I am telling you what I would have done if I could turn back time, and that is not leaving an aggressive note. How would you feel if you were the burping man and saw a note about what you could or could not do?
