This. My old first boss told us that he is happy if we sit at our work places and are deep in the trenches of coding.

I was happy when doing databases on a whiteboard or collecting coffee and fruit from the canteen. Needless to say, I did not feel like sitting in place and hurting my back just to be looking productive.

Hell, I had one complete a*hole of a boss who, one time when I was sitting at my desk, in front of my computer, leaning back in my chair trying to figure out how to make something work, say "there's not a terminal in the ceiling, commandlinefan".
