From The Histories, RELEVANT STILL:
They are very fond of wine, and no one is allowed to vomit or urinate in the presence of another person.
YEP MAKES SENSE!
If an important decision is to be made, they discuss the question when they are drunk, and the following day the master of the house where the discussion was held submits their decision for reconsideration when they are sober. Conversely, any decision they make when they are sober, it is reconsidered afterwards when they are drunk.
OH YOU MEAN LIKE HOW I ALREADY LIVE MY LIFE?
