I couldn't find a source for this but I once heard of an North American company which had opened some offices in northern Europe and used the same satisfaction survey across all offices. They were astonished to see satisfaction scores being so low in northern Europe so they launched an investigation into the matter. The result of the investigation was that satisfaction in the European offices was actually comparable if not higher than the North American offices, but culturally they would use a score like 3/5 to indicate that they had no complaints, reserving higher scores for when things were above and beyond great.

Someone with better Google-fu might be able to find a source because I probably got something wrong but I think that was the gist of the event.
