As you'll see, Alli really blew her stack when they dropped the papers on her, vociferously claiming that she never touched them before confronting the process server face-to-face as he talked to our cameraman. She tries to put on a brave face for the cameras before driving away, but it might have been a futile gesture - by that point, the damage had been done!
