Aulus Gellius, Attic Nights: 11.14.2
“They say that Romulus was invited to dinner, where he drank little because he had business the next day. To him they say, ‘Romulus, if everyone did that, wine would be cheaper.’ He responded to them, ‘Nay, it would be expensive if everyone drank just as much as they wanted; for I have had as much as I wished.”
Eundem Romulum dicunt ad cenam uocatum ibi non multum bibisse, quia postridie negotium haberet. ei dicunt: ‘Romule, si istud omnes homines faciant, uinum uilius sit.’ his respondit: ‘Immo uero carum, si quantum quisque uolet, bibat, nam ego bibi quantum uolui.’
