Answer:
hospitality is mentioned many times in odysseus. it is known as xenia in the poem. one notable example is.
here is a poor man come, a wanderer,
driven by want to beg his bread, and everyone
in hall gave bits, to cram his bag—only
antinous threw a stool, and banged his shoulder
the lines show odysseus disguised as a beggar and shares his bread with another beggar in a weird way because he had to defeat him in order to eat. however, odysseus does not kill the old man and even shows his hospitality.
