I had an issue once and it hade me raging mad. Around 11am or so at the Westin STL, with the dead bolt in use and the little lever lock engaged as well, two housekeepers entered my room while I was sleeping (in the buff!!!!).....I woke up and they were staring at me in all my glory....guess I kicked the covers off at night. Needless to say I did not pay for the room that night.
