I do not fly often so sometimes I don't always understand some procedures. But there was a TSA agent at security who literally spoke to me with a huge attitude and spoke as if I was a child. She was extremely rude and embarrassed me by yelling that I hadn't done something right. I told her I was sorry and that she didn't have to be so rude about it and she told me I was being too sensitive! Like, seriously??? I have already filed a complaint. I realize that most likely nothing is going to happen but still......there was NO need for that!
