I remember once as a junior developer meeting up with the head of technology to rely a project update to him. During the meeting his (desk) phone started to ring. He looked down at it and pressed the mute button for the ringer. While commenting that they don't get to jump the queue just because they're phoning him.
At the time I found it reassuring that I had his undivided attention.
