No more Fräulein - BIG GOOF
In the Zermatt hotel Pine keeps addressing the female hotel clerk as Fräulein. In the 1990s the German language authorities got rid of that assignation. It only exists in old films and books. It is not used anymore. It is considered improper and impolite. In real life the female clerk would have taken him down a peg or two, and sued him for sexual harassment after having slapped him silly. The hotel scenes took place in 2015, not 1915.
Stupid tv writers and producers don't do proper research.
