Arrived on Austrian from VIE Saturday afternoon in October. The mobile people mover was very crowded and slow. Three different hurdles to jump; customs baggage retrieval and another entrance through security. TSA personnel were absolutely the rudest most impatient and unhelpful I've encountered in the years since TSA was born. An elderly foreign woman was castigated in front of everyone for daring to have a small (one ounce) bottle of hand sanitizer in her purse. The TSA people yelled instructions which were difficult to interpret in the crowded conditions and generally made my wife and me embarassed for our country which used to have a reputation for welcoming visitors and citizens. There's no excuse for this mess which represents entry into our capitol city. I've traveled six continents and never seen worse. At both LAX and IAD the reception of air travelers to our country is in need of drastic overhaul.
