Who tells them how to find Death, and how do they treat this person?

They met an old, poor man at a style, who greeted them courteously. The proudest of the drunkards responded rudely, asking the man why he was still alive at such a ripe age.One of the other drunkards responded still more rudely that the old man was to tell them where Death was, or regret not telling them dearly. The old man, still polite, told the drunkards they could find Death up the crooked way and underneath an oak tree.
