I want to ask about the meaning of a sentence.
RICHARD: Ah. Speaking of which, I’m going to give that man a call.
ALAN: Richard, you’re getting yourself all worked up.
RICHARD: As long as I’ve been with this company, it has been run by gentlemen. Revising a man’s work without so much as a phone call would’ve been unheard of!
The sentence that I don't understand is "Revising a man's work ... would've been unheard of!". I guess Richard is saying that giving a phone call is not a big deal. But I am not exactly know how to analyze the sentence. First, what does "so much as" mean here? I find two meaning for phrase. Merriam- Webster says it means "even" and Cambridge says it means "but rather". Which is more suitable here? Second, what does Richard mean when he says "would've been unheard of!"?
What does "so much as" mean here?
The key to understanding that is the word without immediately before it. without so much as can only mean without even, and not *without but rather, which sounds really strange and meaningless.
