Yes, it's got all sorts of nutty dialogue. The bits between the husband and wife on post-apoc morality are great.

Harry: Look sweetheart, for the next weeks survival is going to have to be on an individual basis.
Ann: What do you want to do, write off the rest of the world?
Harry: When civilization gets civilized again, I'll rejoin.

The family's next stop is to buy provisions for the long haul. After spending $190.03 on groceries, they head for the hardware store where Harry's pragmatism really begins to take center stage. The friendly, 30ish store owner, Ed Johnson (Richard Garland), has just learned of the attack and solicits Harry's opinion, "figure L.A.'s had it?" he asks.

Initially, Harry tries to be cagey and answers, "I don't know," but then sends up this flare: "say, where do you keep your hand guns?" But Johnson isn't very swift on signals and winds up taking Harry's IOU for goods and services at gunpoint. Son Rick joins the fun by covering Johnson with a rifle. Despite Harry's assurances that he will repay his debt, Johnson sneers, "In my book you're just a thug."
The hardware store heist leads to more nagging:
Ann: After all these years I thought I knew you but you turn out to be just another stranger."
Harry: My family MUST survive!
Ann: (Disgusted) Getting your son to hold a gun on a man.
Harry: Drop it Ann!
Though firm with his wife, Harry cautions Rick not to get too carried away with their father and son crime spree: "Don't write off the law - it'll come back."
