It's a childhood story dressed up in sci-fi. If an American child had told it, they might have said they demanded baseball cards, and the amused captain would have given them food, booze and "lots of baseball cards, of course". Children all over the world occasionally make demands of adults and are thrilled when the adults oblige them; their bold dare paid off! Children make up games at school, so when all the chestnuts fall off the trees, children make a game from the mass availability of chestnuts.
It's a British story - it's ostensibly space opera, but really it's more a space-themed Radio 4 comedy. It's British by default. Hence bypasses, council planning departments, stubborn bureaucrats, substances almost entirely unlike tea, solving problems by going to the pub, moaning about the weather, cricket stoppages, getting drunk, implacably morose people, smugly insincere corporate drones, being annoyed at overly flashy Amer... people like Zaphod, and so on. And conkers, of course.
It reminds me of the Twitter thread by an American who had never heard of boarding schools asking "what did you think in Harry Potter was magical but it turned out just to be British?" [to which someone said "Scotland" :(]
