It's amazing how much the Shadows House's management style is helping the good guys with the coffee situation - the Star Bearers want to hide it from Edward because they're afraid of the consequences, and then when Edward finds out, he himself wants to hide it from his superiors, because he's also afraid of the consequences.
Moral of the story: don't have a management style where your underlings are afraid to tell you bad news.
And wow, Edward really does just wear the same suit every day, it's not just the mangaka not wanting to come up with new outfits.
