The custom of serving bread and salt to guests is a recurring reference in George R. R. Martin's A Song of Ice and Fire novels, where the welcome ritual serves not only as a Westerosi tradition of hospitality, but also a formal assurance of "guest right", a sacred bond of trust and honor guaranteeing that nobody in attendance, hosts and guests alike, shall be harmed. Violating the guest right is widely considered among the highest moral crimes, an affront worthy of the worst damnation, rivaled only by kinslaying. Game of Thrones, the associated television series, prominently features the tradition in season three, episode 9, "The Rains of Castamere".
