After reading this again, it seems you had words with this individual. It looks to me as if you engaged in a verbal duel and were not prepared when the other party went physical. It seems that a much better course of action would have been an apology VS "Chill Out" and whatever else might have been said. You had been fishing all night, were you also drinking beer as you fished?
As I was walking back to the truck another vehicle pulls up, the driver gets out and immediately starts yelling what the f. I told the guy we had to lay the rods down to chill out. He screams Ill f you up. I tell him we are not interested in fighting we came to eat an there wasnt going to be a fight. I then started walking towards my truck again, as I see him waiving more people over. I got back in the truck and pulled up to order, as I start ordering I see someone running at my truck, I reached in my console and grabbed my g23 with a tlr3 weapons light mounted on it. The guy is right on me by now and grabs me by my shirt with one hand and choking me with the other.
