I believe the focus of the argument is that:
(1) The 'staff' told an unidentified/unknown caller that she was there, and what room she was in.
(2) The 'staff' booked him a room right next to hers.
(3) The 'staff' had been modifying the peepholes for their own devious purposes, which is where he learned how to do it.
like i said, i read the article twice before posting and don't see what made them liable...
