From Albanian Assignment: The Memoir of an SOE Agent in World War Two, by David Smiley (The Extraordinary Life of Colonel David Smiley Book 1; Sapere Books, 2020), Kindle pp. 48, 51:
Skender Dine, Gjin Marku and I stayed in four different villages, and I was able to observe, as well as learn from my escort, a number of Albanian customs. The most important concerned the laws of hospitality. On arrival at a house the guests would be met at the front door by the host, who immediately relieved them of their weapons, which he would usually hang on a wall of the guest room. This gesture meant that from then on, the host took upon himself the responsibility for his guests’ lives. I slightly cheated over this custom, for in addition to the big Colt .45 automatic in my belt, I always had a small .25 that fitted into a hip pocket without showing.
Besa was the Albanian expression for these laws. If, to his unending shame, a guest was killed while under his protection, the host would then have a blood feud with the murderer and his family. Until this was avenged, the host could not clear himself of this dishonour, and his neighbours at meals would even show their disapproval or contempt for him by passing the coffee to him under their knees (a symbolic action implying ‘I piss in it’).
On leaving the house the following morning, the host would usually accompany his guests for the first mile or so of their journey, and it was not until he had said his farewell and turned for home that the beza was no longer binding.
