I was waiting for my friend at Grand Central Terminal yesterday morning and I saw a cop standing guard in the NYPD booth in the building. People kept going to the booth and asking him for directions. That seemed like his only job all day. So, I started wondering if he liked working there at all. Did he hate his job? After all, his work could have been easily replaced by anyone who knew his or her way around the city (it's just like an information booth in Times Square!).
