I hate when people make rules and policies that are strictly for appearances. If I'm cashiering and there is literally nobody in the store, why can't I read a book or listen to a video? Why can't I sit down? Who am I bothering?? I can't sit idle that long. “Busy work” is so dumb. Let people do something actually productive. How much time is wasted doing meaningless tasks or standing around for the sake of it? Nobody cares!! I'm not even going to notice! As long as you do your job when there are customers, why does it matter?? Sigh.
