If you asked him, hospitality wasn’t quite food, drink, and fire, like a body wasn’t quite bones, flesh, muscles, and whatever else a body was made of. You needed those things, true. The stories generally agreed it was the bare minimum requirement, good enough for the purposes of Zeus, and who was he to argue with that? But you risk missing the spirit of the thing, and in doing so, you might miss the act entirely. Compare a random box of seeds and fruits, thrown in front of whoever walked in, to a meal prepared out of whatever resources one had, made for the purpose of feeding your guest. Compare the constant, middling burn of a chemfire cube to a fireplace tended carefully, burning neither too hot nor too low, that your guests may sit in comfort all through the night. 

…didn’t it also require shelter of some kind? A home? A place of relative safety? Since you could offer the hospitality of an open campsite, you didn’t need a roof per se. But you did need a space that was mostly your own, where somebody else could exist in peace.

If you asked him, the bare definition of the concept was lacking, possibly critically so. 

[i]If[/i] you asked him. But why should the Royal Architect ask the opinion of a chef plucked from the backwater town of Beri? About all he knows is his manners. His bow is lower than his higher-ranking companion. He is going to continue staring a hole through a floor the drone swarms tore apart as if it were paper. He will continue to ponder the wonderful mysteries of crackling fireplaces and bubbling pots of homemade stew on a cold night. He will not make a [i]sound.[/i]

Unless you ask him.
