and giving them a hard time is unjustifiable,
Bollocks. I'll give anyone a hard time if they aren't polite enough to acknowledge me saying hello to them when they approach me for whatever test they have in mind. I'll do the same to the refueller or the Engineer or my line manager. Manners don't cost anything and if some basic manners are on display the whole thing goes smoothly, the thing is , the refueller and Engineer and line manager are polite 99% of the time, Security about 50% of the time.
All the various agencies are doing is making sure the next time something is attacked, it won't be an aeroplane.
I don't agree. Do you think that every person airside in Australia has been through an x-Ray machine?
