It's 9am on Monday and Bob is sitting in Terry's large office; the early morning sun is streaming through the half-closed blinds and casting some shadows across Terry's big black shiny desk. It's annual performance review time. Everyone is on their best behaviour. There is a degree of tension and apprehension around the office. In the chair opposite Terry, Bob looks like he is sitting in the airport lounge, having just been told that his flight has been delayed an hour and it is already 10:30 at night.
