Horrible experience at the TSA checkpoint today. They were very rude and aggressive. One of my friends I was traveling with was behind a couple of international travelers that didn't speak very good English the TSA person was very rude and made a comment about "making" them understand. This was after making some people walk from the other side of the TSA to ours and then they decided they were shutting our side down so they made those people walk back to the other side. I was yelled at because they wanted me to go through the metal detector but the lady wasn't specific as to who she wanted to go through it. It was a horrible experience and will probably try to avoid the Las Vegas airport as a whole.
