"They" say breakfast is the most important meal of the day. Well, "they" and Dave clearly are not on the same page of the menu. On the other hand, while Johnny is enjoys a hearty classic breakfast, he is already thinking about lunch, dinner and the snacks in between. It's not that Dave doesn't like to eat, "au contraire mon ami," it's just that the morning meal isn't his "thing" and thus he misses out on the cavalcade of solitary older men who go to McDonald's and stare silently out the window while ingesting a serving of eggs shaped like a hockey puck.
