Is the ATC too sharp?

[MathFox]

Here Schiphol tower is calling the plane before the pilot is seeking contact; translation of the first Dutch sentences:

Do I hear the KLM1286?
Not yet, but I am happy to reply to you, we are established on the right

I found the entire conversation somewhat curious and would like to hear your comments on it.

[Pearson]

Um, there's nothing of significance here whatsoever...
