Changes

At petrol stations you should definitely try to talk to people, which will probably work out fine if you don't dress up like a hippie. Many people will not stop their cars if you stand with the board but will take you if you ask them in person (which is a general hitchhiking principle). Try to speak in Dutch or English. French and German often work too, but not as effectively. Most likely the Dutch people will avoid you while speaking in German. In the Netherlands, there are as well a lot of seasonal workers and immigrants. There are particularly a lot of people from Poland and Bulgaria. Thus, it is fairly easy to get a lift for instance straight to Poland if you know the language or are communicative enough to sway Polish people to take you.
