@nprofile1q... "There aint no such thing as a free lunch," was acronymed to 'TANSTAAFL' by Robert Heinlein in his novel 'The Moon is a Harsh Mistress'.
So, while I agree the saying itself is more evocative, I've gotta allow as TOFCIITM — which does sort of look like a Ukranian word — doesn't roll off the tongue quite as trippingly.
