Based on the given information, it is not explicitly mentioned whether Hans knows Shoshanna at the restaurant. The details provided only mention his actions and choices, but there is no direct indication of his familiarity with her.
While he ordered milk and cream for the farm girl, it does not necessarily imply that he knows her personally. It could simply be a gesture of kindness or a general assumption based on her appearance as a farm girl. Similarly, butting his German cigarette in the strudel does not provide any direct evidence of his knowledge about Shoshanna.
Without further context or information, it is difficult to determine if Hans knows Shoshanna or not. The given details only shed light on his actions and choices at the restaurant, but they do not provide any clear indication of his relationship or familiarity with her.
In situations like these, it is important to gather more information or context to draw a definitive conclusion. Without additional details, it is best to refrain from making assumptions about Hans’ knowledge of Shoshanna.
