… and we get the situation of BATNA introduced later ;).
If the antique dealer is not stupid, he should assume that he can sell the table for at least 50€, otherwise he would not buy it. This assumption might be wrong, but that would be another issue.
I do agree that this introduces the BATNA situation later—but that’s so general that I actually can’t think of any reason that isn’t considered “BATNA” for why the dealer should never accept less than $50. Maybe I just need to open up to more creative situations: the Mafia mob wants to keep table prices up and so threaten to shoot him if he sells it for less than $50; or the government decides that a fixed Table Tax was necessary so that each table was taxed $50 regardless of the price it was sold at; or he wants to signal that his goods are of high quality and so considers any price less than $50 to be too low for his store. Okay, on second thought this has turned into a pretty good example of why I should never say “I can’t think of any examples” without at least first trying to think up some examples.

When I started my current job, I developed the ritual of writing email to the developer whenever I had a question about how code worked. Often, the developer no longer worked for the company, which didn’t matter, since I never sent the email anyway.
What I found was that I would write emails like “So.. I notice X, and Y, and Z. Which seems like they contradict each other. Of course, it’s possible that A is also true, which would explain it, but if A were true I’d expect to see B. Which...” (research) “I do indeed see. So, um, never mind.” and delete the email.
Eventually I figured out how to have that conversation entirely inside my head, but it took quite a while.
I am particularly fond of the framing that among “hackers” the value of a question is presumed to be in what it teaches. The authors don’t say this explicitly, but this contrasts sharply with the wider culture in which the value of a question is presumed to be in that it increases the status of the person being asked (whether they can answer it or not). Much of the intercultural communication failure around asking and answering questions can be traced back to that.
I’d never heard that expression, though I was familiar with the technique (with a teddy bear, though, not a duck). That said, I wasn’t actually programming at the time, just trying to understand what the code did.
I think I’ve seen it explained with a rubber duck more often, but I learned it
first with a teddy bear too, probably on page 123 of Kernighan & Pike’s
“wiener dog book”:
Another effective technique is to explain your code to someone else. This
will often cause you to explain the bug to yourself. Sometimes it takes no
more than a few sentences, followed by an embarrassed “Never mind, I see
what’s wrong. Sorry to bother you.” This works remarkably well; you can
even use non-programmers as listeners. One university computer center kept a
teddy bear near the help desk. Students with mysterious bugs were required
to explain them to the bear before they could speak to a human counselor.

Upvoted for this.
This often happens to me:
“Hmm...”
Thinks.
”I can’t think of anything.”
Tons of ideas spring to mind.
Sounds like my thing where I can only locate objects after the ritual of saying “hey where is the”.

Eric S. Raymond and Rick Moen make a very similar point in How to Ask Questions the Smart Way.
That’s a lovely essay; thanks for the pointer.

This is called rubber ducking.

Yes! That’s exactly the anecdote wherein I first learned it.
With regards to the Table Tax, what if there are storage costs to the table, so its value unsold is negative?
