German Court Etiquette

One often reads that many of the German houses were stifling in their formal etiquette. 

Courts such as Saxe-Weimar-Eisenach and Mecklenburg-Strelitz are examples where strict and irrational formal ritual served to alienated and victimised its own members.

I was wondering if anyone could provide some specific examples or anecdotes, of German court etiquette.

Thanks
