I'm glad to see I'm not alone on this. Unfortunately I'm being backcharged the difference of this and the room area. It seems the national thinks that anything over the room area is considered excessive and will not pay.
This is another, learn the hard way for me and I'm not sure how I will go about bidding in the future. Obviously they are wrong in backcharging for this and I have the to option to not work for them but that's not the direction I want to go. It seems once they make up their mind on a backcharge, no amount of explaining will change their mind.
