Me too.
I got fired from my first job at 16, at MacDonalds. The reason I was fired was that I was told I was "too efficent" at the cooking end of things. I had it in my mind that the burgers should look identical to the way they looked in all of their advertising. So I took additional time to put all the toppings and everything on so everything was perfectly proportionate and symetrical. Turns out speed was the name of the game as they were selling "fast food".
