I had a thick metal case that had once contained a very old computer. I put it beside my trash barrel and went out to stand with it as the truck pulled up. The driver looked down and said, “I can’t take that.”

I pulled out the twenty I had stuffed in my pocket before going out. I raised my eyebrows.

The driver hopped down, took the twenty with his left hand and the metal case with the other, got back in the truck and waved goodbye.

Of course he knew he could get a few dollars for the metal, too.
