If someone is going to become so obese that they cannot fit into a seat, they should be the first ones to be inconvenienced when it comes to reseating or rescheduling passengers due to their size. If he couldn't put the armrest down, he should have been made to purchase two seats.

No offense intended for our overweight audience, but fair is fair. If I'm paying for a seat, I expect the right to use the entire seat.
