I lost my ID the day before my flight, and I thought I was screwed. I brought as much documentation as I could to prove who I am, and the TSA Agents were very courteous and professional. The gentleman who frisked me was especially polite, and I felt perfectly comfortable. He made conversation and was very clear about what he was doing, which I appreciate. After I was checked, I walked all the way to my gate, only to be chased down by the same agent who frisked me... Apparently, I had left my boarding pass at the TSA checkpoint and he was kind enough to run it to me!
I had a good experience with TSA Las Vegas. They're just trying to do their jobs and go home to their families, and I think we should try harder to be understanding of the challenges they face on a daily basis.
