My ex wife is famous for that ! Everything is a big deal to her, especially if it comes to money and she wants some.
Well, there was maybe just this one time...
I was working for a Japanese company and stuffed up. The boss came to see me and said, "If you ever do this again I will bring a ceremonial knife into this office and watch you ritually disembowel yourself."
Seemed like a pretty big deal to me.
