Protocol of Gifts
this was the phrase used top describe the custom of the Twi'lek society in which a visitor always brought a gift for their host, as a sign of friendship and in exchange for their hospitality. The custom originated early in Twi'lek history, when different clans first met. Over the centuries, the Protocol of Gifts has been extended from personal meetings to business gatherings and the arrival of a starship to a port such as Kala'uun. Those spacers who failed to provide a gift to Koh'shak or his family were rebuffed.
