Throughout his epic journey, Odysseus is the beneficiary of xenia on a number of occasions. One thinks of the lavish hospitality laid on for him by the Phaeacians, for instance. Since hospitality was crucially important to the Greeks, it was not be taken advantage of. Yet that's precisely what Odysseus does when he arrives on the island of Polyphemus, the giant Cyclops. Here, he (unrealistically) expects the kind of hospitality he received from the Phaeacians.
