It wouldn't surprise me if this was more widespread given my experience working with the US government, and everyone else I know that has worked with them has similar stories. When I did a contract for the FAA My coworker said to me sarcastically: "They take two hour lunches then take off Friday and still somehow manage to get 40 hours in. I only wish I knew how they did it so I could do the same"

Edit: Thanks for the downvotes. I'm sure your experience working with government is different.. Oh wait, you've never worked for them because if you had you'd know I'm right. I've lived in DC almost my whole life and I've got connections in almost every institution. If you think they're sharp as shit and work really hard you're in for a gigantic surprise.
