Describe symbolism in Thank You for Smoking by Christopher Buckley

The changes in location throughout the novel reflect changes in the tone of the narrative. Washington DC is a menagerie of lobbyists, politicians, reporters, and ex spooks. In essence, it's a powder-keg of methodical schemers with hidden agendas. Los Angeles, on the other hand, it all on the surface with people like Jack Bein. It is
kinetic, bombastic, and laughably shallow. Winston-Salem, home of the Captain and the actual tobacco farms, represents a lost world of Southern manners and people who live off the land.
