Some men don't like it. Honestly, I'm fairly wary of people who are obsessed with it as it always makes me wonder whether they've been banned from a particular hotel or are checking if I have lower security.
Not to tarnish all of them with the same brush, however, I just take extra precautions. Some people are just oddballs or obsessed with the idea of there being CCTV of them doing something... you know, completely legal?
