Three merchants enter a tavern
From World of Entorais Wiki
Three merchants; an Iskandean, Tabarani, and Aralian, walk into a tavern. The Iskandean asks for a flagon of their finest ale, pays the barkeep and quaffs it in one go. The Tabarani asks for a keg of their finest and after paying the barman, sells it to the Iskandean for profit. The Aralian, asks for the recipe, which the barman refuses; so the Aralian buys the tavern.
