re: Have you ever witnessed a fist fight at work?

Fortunately, yes. It got ugly. Where I work, my grandfather at the age of 60-65 asked a 40 YO to put out his cigarette in a no smoker area of our business. The man refused and pushed my grandfather who fell over as soon as my father and uncle were rounding the corner. My uncle, fists up, approached the man and said, "Why don't you take the first shot". The man reared back and punched my uncle in face. My uncle started laughing and proceeded to lay on the punches; he hurt the man really bad. We had to call an ambulance and everything. It was on camera that the man pushed an elderly man to the ground and struck my uncle first. It was a pretty bad scene. It was the first time I had ever witnessed anyone getting knocked out and their head hitting the concrete. He started choking and my uncle rolled him over.
