Reminds me of our, short lived, commercial department. A bunch of account managers in a couple of open plan offices with a glass partition between them. On one occasion I was visiting, can't remember why, and a guy from the office I was in walked to the partition and started waving at someone on the other side. Unfortunately for him he was leaning over the shredder, a large automatic machine as tall as a desk. You can probably guess the rest... His tie dangled over the paper slot and activated the machine which promptly started munching on it. Fortunately somebody near by hit the reverse button. For Catriona's benefit, the office was at the front of TBA so lots of "important" people about at times too.
