Poles will be more likely to ask if "you don't need anything." This, typically, would be seen as rather rude in many other cultures, implying that the one asking is hoping there no immediate needs as it would be a bother to him. It's actually implying that the inquired-about is not helpless and can manage on his own, but it also leaves open a small polite door for the petition of assistance. Another example is "Tell me about the girl/boyfriend you don't have." This seems like a convoluted, illogical statement (and it is), but it's Polish for "Why are you single?" Now, a direct "Why are you single?" is probably a faux pas in many cultures, and this is just how they skirt the issue.
I have found the best way to settle these throw-you-for-a-loop questions is to tackle them head-on. When a Pole asks a stumper, just reply with a, "Are you asking what my father does? He's a lawyer." (NOTE: The author's father is not in the legal profession.) After being confronted with evidence of their sly mind-bending inquiries, the Pole will most likely look a little sheepish and say, "Yes, I am [asking that]."
