Headmaster Dippet's heart is in the right place but he doesn't really get it. Elves, as she has tried to explain at length, don't just need drudgery for drudgery's sake, they need to be of benefit to the persons or institutions they belong to. Dippet had just wanted to scrap all of Hogwarts's enchanted cookware and replace it with free elves, but that's makework, giving free elves makework would almost be worse than freeing them in the first place. They don't need pity. ...Okay some of them could probably do with a bit of respectfully expressed sympathy but giving them makework won't fix the underlying problem.
She's dwelling on this as she's taking inventory of one of the closets.
That's not a closet. That's a bar. She's heard of Hogwarts nooks and crannies getting up to some nonsense but she's pretty sure the Founders did not put a bar anywhere in their magic castle.
