Maybe ask the customer, “can I ask why you would like the one with the smallest box?” instead of making assumptions? Although note that this might also be classified as a question where the person asking is admitting they don’t understand why someone would want this aka “looking dumb” in the wording from the article
That last one makes the most sense, and explains why he didn't divulge it. That way, when the author is raided, they aren't going to ask, "hey, where's that computer that, comes in the smallest box?"
I'm imagining the author has this big book case, and one of the books is hallowed out and has an Apple machine in it. Maybe it's built into a false floor of a cabinet.
I don’t why the author needed a small box, but I did think of my experience when I read his anecdote. I think a large part of his appearing impaired is not even attempting to explain his rationales, suspicions or methods in the moment. His goal seems to be to engineer these awkward interactions, when they could be otherwise lubricated or alleviated. He’s acting as though other people and their understanding are irrelevant to him; they are furniture or fixtures that should trust and obey unquestioningly, which is a bit ironic.
I read his post to the end looking for the answer to why he wanted the smallest box, furiously thinking of why. I could only think of three reasons that I rejected as unlikely. Frustrated, I came here to look at the comments. So many comments about the box. It's like the contents of the briefcase on Pulp Fiction. It's like a McGuffin that forces everyone to talk about his article.
