תּלמוד אויף אסתר 1:8

And the drinking was according to law. What is meant by ‘according to law’? R. Hanan said in the name of R. Meir: According to the law of the Torah. Just as according to the law of the Torah the [quantity of] food exceeds the drink, so in the feast of that wicked one there was more food than drink.

None did compel. R. Elazar said: This teaches that each one was given to drink from the wine of his own country. That they should do according to every man’s [ish, ish] pleasure. Rava said: This means that they should do according to the will of Mordecai and Haman. Mordecai [is called ish] as it is written, “A Jewish man;” and Haman, [as it is written], “A man (ish), an adversary and an enemy.”
