@Linkat,
Ah, yes. I remember a thread about the cubes. I also agree that the employee should have sent a e-mail explaining the situation.
If this is the first time this has happened, I would not be too hard on him. He was in a difficult situation and probably felt uncomfortable with the 3rd level up. He could, however, have indicated that he had an appointment with you immediately after the call.
That may have prompted an earlier end to that call.
