If a question is asked in surprise, informally many people use "?!" as their ending punctuation, as in the following:
What did you do to my sausages?!
According to the accepted answer in this question, this is considered incorrect by experts. In that case, which punctuation ought to be omitted and which used?
What did you do to my sausages!
Seems incorrect, as the question is no longer punctuated by a question mark, but
What did you do to my sausages?
loses the punch of the exclamation mark and thus requires extra words to get the point across.
