Is it ever acceptable punctuation to have both an exclamation mark and a question mark at the end of a sentence? For example: "Why didn't you tell me that before I threw it away?!" If not, is this how a person would get around that problem: "Why didn't you tell me that before I threw it away?" she screamed. One would use a tag to denote the mood of a question? There are times when I want to omit a tag for the sake of rhythm, but if it's completely unacceptable to double punctuate like that, then I shall refrain from doing it.
