I was leaving the neighborhood and the street I was on dead-ended onto a two-lane roadway. I stopped at the stop sign and noticed a work truck driving towards me from the right. The left turn signal was on, indicated that it would be turning on the street I was on.
I began my right turn as the truck began his left turn. He cut the corner, crossing into my path. It was obvious that if I did not stop I would hit him, so I had to brake hard. When I did I spilled my coffee on my legs.
So I sat there with my car not moving while I reached for a towel and said, "ouch that coffee is hot".

He had his window down and was looking right at me. I rolled mine down, and he said, "do you have a *expletive* problem?" I replied that I spilled my coffee, and he placed his truck in park and got out.

He said something about, "what do I wanna do about it?"
There it is, what do you do?
I'll tell ya what I did later.
