Let me guess this was in the C checkpoint and it was a larger gentleman with glasses. This guy is the only one that ever asks and a few weeks ago did the same to me. I looked at him and asked, "why?" He asked again and I told him he didn't need to know this information and to quit making up rules that are not SOP. I told him I wasn't going to give him this info since it was on my boarding pass. He got visibly mad and let me pass.

Soon a "supervisor" came over b/c the guy called him over and asked proceeded to tell me that checkpoint "C" was required to ask this from everyone, (while the new TDC behind him was letting people go thru without asking.) I told him this wasn't SOP and this guy should not be making up his own security rules. The "supervisor" gave me some nonsense about SOP and doing things randomly.

I told him that with my ~100 flights this year, this one guy at this checkpoint was the only one to ask all over the country and again, should not make up his own rules. I told the "supervisor" thanks for the info and went thru.
