It's one thing to try to make a screwed up deal with a grown man. The business with the kid is another matter. If the kid thought he was getting paid and he didn't, and if he stacked three cords and the guy only wants to pay for one, then that's criminal. Perhaps there's a friendly constable who would be willing to visit the place and verify the quantity of wood so the kid can go to small claims with that deposition in his pocket. A local judge might decide to teach the professor a lesson. You can get by with being a jerk for longer in a city than you can in the country -- you make yourself unwelcome in one Starbucks, there's another one a block away. Not the same deal in a farm community. Bad idea to make enemies.
Well said.
