This seems to me the crucial assertion in your OP.
It is based upon the somewhat typical response given when asked the first question or the second statements are mentioned. It was not to suggest that everyone on the planet would give such an answer but it does certainly seem to be a consistent one.
However, yes - it is crucial because the very post is about the inevitable consequences if someone asserts 'gods will' as an answer.
Requests in mundane social relationships can have this character also. Think of the kinds of discussions, including begging
I'm under the impression, given your praragraph before this statement, that you mean something like: The beggar asks for money, you say no, he then pleads with you which causes you to change your mind and give him money after all?
If so I would submit that this comes under the 'sincerity' factor. I'd be ok with that, as explained on my earlier post, and it would certainly save the resulting consequence of prayer being redundant. It would also confirm the quoted biblical statements.
My final statement would be to merely ask if someone could for once actually be serious when praying for all those children in Great Ormond Street Hospital, (eg).
