This was at a large university and the textbook we used had some remarkable dialogues in it. Frequently we read about the life of Pan Orlowski, the director of a company in Warsaw. Pan Orlowski had a 'luxury' apartment with electricity and a heating.
It was odd . If they want to teach a Polish language and give a degree , they should first obtain for their library the appropriate manuals. I do not know, which year this book is from , but the electricity, heating or running water in Warsaw were available and were not any kind of luxury. Perhaps with the exception of the post-war period , when the city was being rebuilt.
Warsaw was in ruins after the war and the reconstruction of the city started after the war . The newly established apartment buildings were equiped with electricity, water and heating.
It is a scandal that you learned about the city life which was not existent at the time you were studiing .
