Your 'friend' should read the T&Cs for the bus pass and see what happens when you misuse it. She'll probably get a fine, which will be a damn sight more than if she hadn't been a fare-dodger and paid in the first place. There may be a delay in her partner getting a replacement pass, too. Could have screwed both of them, and totally unnecessarily as she had no right or reason to use the pass in the first place.
