Thanks Axiom2001, I too (at first) was taken aback, downright offended and thought it was extremely rude of him to not just ask that question but imply that I would be with an unclean partner, and that I would not say something about it. But then, I thought about it better and decided to give him the benefit of the doubt. Not everyone has had the same upbringing or even the same command of the English language or come from the same culture. Thus, I figured either he's not a native English speaker or comes from a culture or household where that sort of unfiltered, rude questioning is OK.
