Supplying the pilot would idle a tractor for a day. That can translate

At $500/gal. one might be approaching the 'opportunity cost' of selling
that fuel to the plane owner.

Still think he's "smart" to sell the fuel at 'only' 10x cost?

Yes. They can ship down a new batch in the next plane, the next day.

I think they should have left him alone in the fuel shed with a 10
gallon for a few hours while they ate a long lunch. But that's me.
