Norway and Sweden are completely different. In Sweden most people either go out to a restaurant for a warm a lunch or eat a warm lunch they brought with from home. An hour lunch break, while not official sanctioned, is hardly uncommon.

And even when I worked in Norway where many people just ate sandwiches for lunch, almost everybody ate lunch in the lunchroom.

Or you sit glued to your computer 6 hours straight, get done what you where supposed to do and go home at 3 to be with your family or get in some other afternoon activities. A very common mindset in Norway.
