Pirovitch looks through the right side of the Cafe window from outside and tells Alfred he can't see Klara's face at first because she is sitting behind a coat rack. When Alfred joins Klara inside, she's sitting at the far end of the window with the coat rack well behind her.
When Klara is wrapping the wallet for her mystery boyfriend, Alfred comes into the room, and she stops to talk. However, when they both leave the room, she picks up the package and it's completely wrapped.
When Klara hurries out of the back room with her hat and coat she rushes past the rest of the employees as they enter the room in a group. Flora is the second-to-last person in the line and she is clearly inside the room before Klara runs past. In the next cut showing Klara hurrying through the store, Flora is the last person in line and is still in the doorway.
After dismissing his employees for the night, Mr. Matuschek sees Vadas leave the shop. As he watches him close the door, you can clearly hear off camera directions that sound like "turn" and "he's gone."
