Imagine you next night trip when you do all that again and you are being escorted to jail and your truck and boat are following you behind a tow truck just because you and him are bumping chest. I guarantee you that his chest is bigger. O.K, so you win and you prove that you don't need a $15 extinguisher. The next time he comes up to you and you show him your proof that you don't need one and his ego is bigger than yours, I'll bet you will be seeing him a lot more. Put one in your boat and he will say thanks and not bother you anymore.
