The idea of hospitality as a duty or moral obligation can be found in a variety of cultures. I found https://en.wikipedia.org/wiki/Hospitality https://en.wikipedia.org/wiki/Hospitality to have some interesting examples. The Pashtunwali code is particularly interesting. Pretty much all cultures have some sort of hospitality notion, but a handful of cultures elevate this to an almost sacred duty.
