That's kind of what I was leaning towards. It's a problem that needs solved, but it's not necessarily hard to solve, nor does it need solved in advance.

It's the kind of problem can often very nearly resolve itself.

Here in the States, I've seen what can happen at the end of the night at a busy Little Ceasers in a not-great part of town. They've got a lot of unsold pizzas, already boxed, that they simply need to get rid of so they can close up and go home.

So they walk out the back door with armloads of pizzas and... casually give them away to the people who are waiting out there. It's a very calm and surprisingly tidy process that goes by quickly. This happens at the same time every night.

The only apparent cost is whatever it takes to maintain the base amount of humility required to let this happen instead of dutifully marching the pizzas over to the dumpster and tossing them in.

This routine is almost certainly an invention of evolution, instead of planning.
