That's reading an awful lot into what I wrote. By the author's own language he appears to bear a grudge against the CBP, so while he sounds polite by his own account he clearly goes out of his way to prove a (valid) point. I don't really see a problem with, most of the time, answering that I was on a business trip and packed my own bags, nor should most people in a "polite society". I don't see how this is being subservient to anyone. Wouldn't a better policy be to assume no problem and only raise the issue if they raise it first? It's healthy for society to have people push back against the system but it's also in our best interest, overall, to have security and part of that security is making judgments based on how someone responds to simple questions.
