This regularily got me into fights with other execs and CEO who said "Stephan, when I go through technology at 8pm there is no one there, don't we know we're a startup?"
When a friend and I was on business in Japan we wanted to meet someone at 11pm at night. We were waiting in the business complex and lots and lots of people were leaving at that time (11pm!), then we got a call he could not leave. What a sad working culture.
