Native Americans living in the great plains had a great appreciation, and near worship for the Buffalo. When they would slay one of the beast, every part of the animal had a purpose. From meat for food, to bones for art and tools, to leather for clothes, everything was used, and nothing went to waste. Even the internal organs were used.
It was not because they were afraid to be wasteful, but because they had such an amazing awe of the beast that they felt it was their duty to use everything they could from such a magnificent animal. It was an honor to them to have this creature as a bountiful blessing, and so they sought to respect that animal in every way, shape, and form.
I don't think that's cheap.
But if you take tons of extra mustard packets and ketchup packets from restaurants because you don't want to buy a new bottle, that is cheap as hell.
