Robert Heinlein is famous for coining the phrase "there ain't no such thing as a free lunch", often shortened to the acronym TANSTAAFL. In his book _Friday_, however, he goes so far as to include this acronym in spoken dialogue (quoted under fair use):
"You sound like your late father. I think he invented tanstaafl."
Neither of the characters react to this at all. So, my question is: does this acronym have some sort of standard way it should be spoken? How are words with double "a"s pronounced in English, anyway? Or are we to assume that the character spelled out the acronym? If so, it seems like saying the phrase would have been shorter, more natural, and more obvious. I find it difficult to assume Heinlein made such an atrocious mistake in dialogue.
