He seems to be in good spirits. Guy got cold-cocked by a loco deadbeat who wanted to skip on a bar bill and Leif was just watching out for his friend when the guy went ballistic. Just like the stupid stabbing idiot who attacked him due to the attacker being a hothead.
I doubt Leif will promote having the book thrown at this guy, just like with the stabber. He is a big softy though no one's fool.
