And we finally get to a place where we may be able to reach some common ground.

I will agree wholeheartedly that "there is no need to be offensive." And I'll set aside the fact that asking me personal questions about my finances or travel plans is something I (and many others) find to be offensive. Now; if you will just tell me how to properly phrase the sentiment, "I don't care to discuss my travel or finances with total strangers; I will discuss any legal compliance issues with the appropriate agency." I pledge to use your recommended phrasing in the future, thus doing my part to defuse any potential confrontation.

Thanks.
