Why is "what's what?" always wrong as a question?

0

When I talk to somebody, and I miss a certain part(word) of the sentence they said, I have a habit of replacing the unheard part with what and ask the same sentence like this:

Speaker: Can you please pass the texta(missed)?
Me: Can you pass what?

Speaker: Why don't you drink coffee(missed) in the morning?
Me: Why don't you drink what in the morning(what-in-the-morning is spoken with a special intonation).

Speaker: What is the time(missed)?
Me: What is what?

The speaker I was talking to was an English guy, and he said you can't say what's what.

What is grammatically wrong with what's what as a question and why can I replace the unheard word with what in other sentences?

Thank you.

1He's wrong, pretty much, though the confusion may be from you not including "the", so instead of "What's the what?" you said "What's what?" Both are correct, though. A politer way of requesting someone to repeat what they said would be "Pardon?" (pronounced "par" as in golf, "duhn" as in garden) – Corsaka – 2020-02-02T12:06:54.560

Note: where Corsaka uses italic font, e.g. "He said what?", that word is spoken with emphasis. – Michael Harvey – 2020-02-02T12:28:46.880
