If you look at this from a different angle, we have a distraught lady yelling at a dysfunctional poor family who do not watch themselves around their children and so while this kid is trying to enjoy his cheap snack these instigating parents perturb that driver and as we are aware with kids they're impressional so using what he had and what he learned he was acting like his drunk father who eats the worst junk onto this distraught woman who could represent the kid's mother. We hear laughter in the background too, most likely the mother is laughing out of relief seeing someone else take the pain she has had to endure from her husband these past 3 years. /me rates funny
Hey, man, this is the closest thing to the reality of the matter aside from the fact that it's just a kid telling a woman to khs.
