I am astonished to see that
(1) their VDB offer starts at $250 USD
(2) VDB offers are negotiated with passengers individually, and even when you explicitly ask, they don't match the offer they agreed with another passenger. I mean, there are a whole plane of passengers to load, and the agents are taking the time to fight for $50-$100 zoo dollars. Do they get a bonus for giving the passenger less voucher for VDB?

Is this yet another characteristics of Continental, beside the landing skills of their pilots?
