I worked on a project for a big Korean company that required me to work onsite with a team in Dusseldorf. I happened to be there over Easter weekend and the project was behind. I inquired as to when we would meet up to keep working, and they told me the office would be closed, so naturally I asked what coffee shop/cafe/space or whatever we'd work at instead.
The team there was shocked and maybe offended even, and I was informed it was verboten to work any of the next 3 days.
Differences in work cultures globally are staggering.
