I've seen a few cry babies come into the embassy/consulate and leave claiming this would cost a lot of money -- which it would. Maybe they shouldn't have come in with a passport with X days left with a ticket going back to the US in X+10 days.

I'd be curious what ACS would do -- for example in the event of an emergency -- where a US government blacklist prevents the issuance of a US passport to a citizen without override authorization from elsewhere, an override authorization which can take some time to come in. And names being added to blacklists between departing the US and attempt to get new US passport has happened.
