It's been like that at most of my jobs. I always did my job quietly and efficiently. That seemed logical to me. After some years, I realized some people got attached to performance. I didn't like doing it, and still never got used to doing it, but it got to the point where I felt like a display of emotion was necessary for every assignment.
The quicker I could get a job finished, the less valued the product would be. But if I could roll my eyes, curse under my breath, and watch the RS game for two hours, someone would pat me on the back and tell me what a great job I was doing. /end of rant/
