A local joint in my area did something like this last year. A five dollar burger with two patties, and one dollar per extra patty, no limit.

I’m sure in practice there would have been a limit, but we got a lot of burger for twenty dollars that day. It came skewered and served on its side in what I’m guessing was a submarine sandwich tray.

Copper spools have the sheathing stripped off, wire cut to reasonable lengths, then brought to multiple recyclers in stages.

To be sure, the odd idiot will show up with a unadulterated spool and try to get paid, but most that go to the effort of abducting these things off the side of the road aren’t entirely stupid.

Then again, a less scrupulous yard might still buy the spool as it comes and strip it themselves.
