Arghh! I really hate it when those that do not fly purport to be the definitive expert at things such as TSA screening procedures, boarding procedures, carry-on requirements, etc. While I am no where near a million miler, I have managed 75k for the last two years, but, sigh, evidently I am not expert enough for some. (rolling my eyes) thankfully, I don't have to interact often with them, but just enough that the cumulative effect only gets to me a few times! Even better, I do not have to travel with them!
