I witnessed an old man fight at walmart

I've always seen those public freakout videos on youtube but this time I'm seeing it in real life. They were fighting over parking and the one was really aggressive threatening and shouting. The other man tried dragging me into it because I was walking by and I said im not getting involved. A woman told the aggressive guy to grow up there are children around here and he said F those kids. I was almost in the store when a manager came out. No idea what happened after.
