The Bodhisatta once had a friend who was a tavern keeper. One day the tavern keeper made ready a supply of strong spirits and went to bathe, leaving his apprentice, Koṇḍañña, in charge. The latter, who had seen customers send for salt and jagghery to make their drink more appetising, pounded some salt and put it in the liquor, hoping to improve it.
The story was told in reference to a friend of Anāthapiṇḍika who was a tavern keeper, whose apprentice did likewise. J.i.251 ﬀ.
