I enjoy reversing these attempts.

Just yesterday a passenger tried to psych me out. He looked over and said, "you're not profiling now right?" He thought he was smart because he "made" me. Instead of making up some B.S. and pretending that I wasn't a BDO, I engaged him in a conversation about SPOT. He said that he thinks it is illegal because he believes that we are secretly profiling. I told him I was sorry he felt that way and I assured him that the work we do is cross-cultural and solely based on behavior. I sincerely enjoyed talking with him and wished him a good trip.

It was interesting to hear his voice pitch change and his words become shaky after I engaged him instead of backing down or looking away.
