I advised that my son opt out of the MW machine last week and informed the TSO that I would be videoing the patdown. The supervisor informed me that it would be fine for me to video it, "as long as I don't get the TSO's face or badge number in the video". I said fine, but it really wasn't possible to avoid getting both in the video from the place where he said I could stand. He kept looking at my screen and telling me that I had to "stop getting his face in". I tried to comply with that but paid more attention to getting what I wanted on video. The supervisor insisted on engaging in conversation with me during the time, and in full disclosure, I was not very nice to him. I even referenced my concern for my stuff being stolen by the TSA. It was difficult to remain cool, as I watched my 16 year old being inappropriately touched by a TSO. At the end of the patdown, I stopped recording, and then the TSO said to my son: "Now, I had to do an extra thorough patdown on you [pointing over to me]. Normally, this is like 'bing, bang, boom' and it's done." I immediately asked for the FSD. 15 minutes later a TSA manager came (in plain clothes). I asked him for the FSD. He told me that he was "unavailable". I asked him to confirm that he understood that I was asking for the FSD and he is refusing to get him. He asked me to hang on and left for about 5 minutes. He came back and said he was unavailable. With nothing else to do, I told the manager what happened. He told me that it was inappropriate, and that he would "take appropriate action". I was straightforward with him, and let him know that I was not nice to the TSOs, but retaliation against a 16yo is unacceptable, especially when it involves physical contact with him. I asked him for the TSO's name and he gave it to me. What, if anything should I do next?
