I used to refuse to remove my shoes. I finally gave up since it's faster and easier for me to just do it, and easier on me to not get PO-ed about it. Though I agree completely. The cig lighter rules are equally stupid.

I don't go through the puffer at SFO.

BTW, I believe that if the machine finds (sniffs?) something, the doors won't open on their own. The device also serves as a "man" trap. (or should I say "person" trap?) Anyway, they don't really have to watch you in there. Maybe if it finds something serious, it should just activate the disintegration beam?
