Whenever I opt out (which is every time they try to send me through the scanner) they always attempt to take me to a "private" screening room for my "privacy" concerns. And every time I insist they do it right therein front of everyone, at the table where they're looking through my bag. Mostly because I don't trust what's in a "private" screening room, and partly because I think if we're gonna do this...then lets do this all the way.
