Airline to give man's prize money to charity - Yahoo!7
A man who won $15,200 on an airline scratchie will have his prize given to charity after he ate the ticket in protest.
Is after he ate okay? What about "because he has eaten" instead?
Even if we understand 'after' with a time meaning, the word itself makes the sequence of the actions clear, so the past perfect is not essential.
