Dunno. My wife and I have had unfortunate experiences with TSA. For some reason they just love to pull us and our bags for more thorough searchs.
I've been pulled aside for the more thorough search as well. Even those have gone fairly quickly and pleasantly.
I usually comment that I fully support their actions, and follow their instructions without eye rolls, criticism, cursing, or the general obstinant grumblings that many others can't seem to contain.
Perhaps that gets me thru more quickly and politely. If I had their job I would probably make the grumbler and rude participant jump through a couple of extra hoops.
