[The Squatter of Amon Rûdh]

This is how I would imagine schedules are kept in Mordor:

Khamul: My lord, this is an unexpected pleasure. We are honoured by your presence.

The Witch-King: You may dispense with the pleasantries. I am here to put you back on schedule.

Khamul: I assure you, lord, my men are working as fast as they can.

The Witch-King: Perhaps I can find new ways to motivate them.

Khamul: I assure you, Lord; this fortress will be operational as planned.

The Witch-King: The Dark Lord does not share your optimistic appraisal of the situation.

Khamul: But he asks the impossible. I need more men.

The Witch-King: Then perhaps you can tell him when he arrives

Khamul: The Dark Lord is coming here?

The Witch-King: That is correct. And he is most displeased with your apparent lack of progress.

Khamul: We shall double our efforts.

The Witch-King: I hope so for your sake. The Dark Lord is not as forgiving as I am.
