My question...
When you opt out and you wait for the pat down, what about your belongings? Can you keep your eye on them? Does TSA get them for you? If there is a line of people waiting for there sexual groping, I can see carry ons stacking up at the end of the x ray.
If I opt out and I can not see my belongings, I am going to collect my stuff first then come back. I have already had stuff stolen once, not going to happen again. If TSA has a problem with that, tough.
