I don’t know, but I’m somehow sorry for the window installers...They just don’t go on any tricks. And the letters are stamped with the inscription "Notification", and the papers are thrown behind the signature "Administration".. and three cartridges. Then a man knocks at the door. And he said in a loud voice: "Yes. You will change the windows tomorrow. 25% is paid by the administration." Unfortunately I’m probably stunned.
