Yes in that draught the shoe is on the other foot.

I was suggesting something of a middle ground.

E.g.

JERJERROD (wearily) : Lord Vader this is an unexpected pleasure, we are honored by your presence.

VADER : You may dispense with the pleasantries, I am here to put you back on schedule.

JERJERROD (brusquely) : That will not be necessary, we are on schedule, my personnel are working as fast as they can.

VADER : Perhaps I can find new ways to motivate them.

JERJERROD : We are understaffed as it is. Your methods would have... a detrimental effect, this station will be ready as planned.

VADER : The Emperor does not share your optimistic appraisal of the situation.

JERJERROD : I am in regular communication with the Emperor and he hasn't said anything to me but if we had more men then...

VADER : Perhaps you can tell him when he arrives?

JERJERROD (nervously assertive): I intend to.

VADER : Good, the Emperor isn't as forgiving as I am.

That makes the dialogue half way between his dialogue with Tarkin and Motti in ANH and pretty close to how he and Ozzel conversed.

So what would be the dramatic purpose of this?

We have a Captain talking in a way that makes both Vader and the Emperor less intimidating. He talks back to Vader and is ready to go meet with Empy, whom he talks to all the time. So the Moff, who has no real role in the bigger story, looks a bit cooler at the expense of the main antagonists. What is the benefit to the story?
