Take that for whatever you want. It can be a problem if you are just trying to have a weekend. We don't know how to leave work at work most of the time. But I very much appreciate being serious and focusing on work during regular work hours. one of those big factors that makes most of the places I travel to "nice to visit, but wouldn't want to live there".
 and granted I haven't traveled every where. I understand Japanese salesmen are like this, too.
