He sat there and was really stubborn about moving. The FA had to inform him that due to the seat being a crew rest, the flight would not take off with any passenger in that seat, before he went to coach in a huff.

To my eye, that's borderline grounds for de-boarding, you know that passenger is going to make the FAs' lives miserable the entire flight.
