Why sit and twiddle your thumbs for an hour (increasingly becoming upset with your business partner) when you can whip out your laptop and get some work done instead? Or your cell phone to talk with the family/friends?
That's something you can learn by being involved in the north american corporate workforce.
When I took my very first job at mcdonalds I was told "If you've got time to lean, you've got time to clean."
That work ethic is very prominent in american culture.
If you're not working, you're not achieving your full potential. And that needs to stop.
Sketch out a new idea perhaps? Daydream? Read the paper? Or your favorite blog? It's not "wasted time".
All I am saying is it's not the end of the world that somebody is "late". And that having free time isn't a burden if you know what to do with it.
