That's a great example of a specific factual incident!

But, A.) you don't know if these "facts" are true, so they shouldn't really add much weight, and B.) not all situations come down to something so specific and citable. Sometimes, people are just really obnoxious to be around, and they're rude and impatient and temperamental and it's a daily thing and that's all there is to it, and you can't really boil that down to such a nice clean sentence as in your example.
