If it is true that Dao and his wife initially volunteered, but then retracted when they realized they would not be able to get home until late the next day, I wonder why the United employees did not just ask for another volunteer. Someone still might have accepted if they had just asked again. (And it has also been reported that someone did, but UA refused to give them the $1,600 they wanted). Instead it sounds to me like they went the route "oh no, you already said you'd get off, so GET OFF" and here we are. Not facts, just my opinion.
