I was consulting my grammar book (A Dictionary of Intermediate Japanese
Grammar), when I came upon the following passage (page 323):

Now this is all well and good. But it's a bit conflicting with an explanation
in A Dictionary of Basic Japanese Grammar, in the section about ので (these
books are in a series, by the same authors). Here's the relevant explanation
(page 329-330):

This section is rather explicit that ので is unusable with requests, advice,
suggestions etc. My Japanese teacher has also said that ので is unusable with
advice.

I suppose then the question is, what is the truth? Is the original example
sentence natural? Grammatical? Is there a deeper conclusion to draw here?
Maybe から is inappropriate in such a polite request? Am I missing something
very obvious?
