That's an ethics call you have to make. In the "no, but" approach, I see no harm in it - compliance does not result in a negative result for the other person.

You're not going to do it anyway, but they're going to feel better about it than just a simple "no". In "because I have to make copies"... your call. I wouldn't, because I'd consider this improving my result at the expense of yours.
