Yeah but swedish people are insane when it comes to be on time. It's like you'll go to hell and burn forever if you're 5 minutes late once i your whole lifetime.

The upfront cost is too high for the benefit IMO (I am swedish, and I'm automatically always on time).

A better way? The french way maybe? Let people arrive 5 minutes late until everyone is present, in the meantime chit chat with coworkers. You get to know people and it's low stress.
