That could have been satire it's so wrong headed.
I agree, mortdooley.
From his exaggerated demonstration of his intimate knowledge of Starbucks Order Placing Nomenclature to his foot stomping tantrum demanding the owner do something..at least make sure the weapons are unloaded does seem like a satire.
From the lack of a "punchline" meant to indicate the satire, I can only assume he was trying to be sincere. He demonstrates a petty existence concerned with petty details like who's who in the local coffee shop.
He no doubt resents having his fairy tale world of sipping a large coffee of the day from a venti cup intruded upon by some "fit looking young men" who must have seeped into his existence from some other world of harsh reality. They deserved it when he "looked hard at these guys"
Sigh.
