From Athenaeus’ Deipnosophistae (The Learned Banqueters) 1.8.d:
Ἀντιφάνης δέ φησι·
βίος θεῶν γάρ ἐστιν, ὅταν ἔχῃς ποθὲντἀλλότρια δειπνεῖν, μὴ προσέχων λογίσμασι
Antiphanes (fr. 252) says:For this is the life of the gods—when you have the chance to eat someone else’s food and not worry about the bills.
