Yep, just had this actually happen to me. Blew up on someone in the company parking garage and did not know he was a friend of the firm. He in turn told my boss who then brought it to me. Ended up filing an 'incident' which will prohibit any raises and limit bonus for the next year.

I did not loose my job or end up poor but I bet that guy is thinking "what an idiot, what were you thinking" not knowing how this did impact me.

Prob a poor anecdote but damn did I learn my lesson. Especially since it impacted me financially.

We all make mistakes, financially or otherwise. The point is that we should learn from them and not keep repeating them.
