I always opt out of the body imaging machines but today I got a new response.
After I opted out they had me go through the x-ray to wait for a TSO to pat me down. After waiting a while a TSO comes up to the one waiting with me and asks "Did he set off the x-ray?", "No." "Well then let him go because he would be too tall for our machine anyway."
I happily complied and went on my way, but this has never happened to me before and I'm wondering if I can use it to my advantage in the future. I'm 6'7" an haven't ever gone through the machine so I don't know if I'm in fact too tall.

Has this happened to anyone else before?
