I don't think screwing up your take off by using a taxiway iso 36C is a particular Dutch thing to do....
What really worries me is the fact that TWO people on the flightdeck missed all relevant markings and runway lights and where able to take off with clearance/ without any intervention from the tower.
Having worked for KLM as an f/a for over 12 years i always felt that the people upfront took there job pretty serious so it really came as a surprise.
