I really think that you are losing the plot here.This Post is not about the rules but about the rules being applied to flight crew.
If you don't like complying with the rules, get another job.
If you think the rules need to be changed then lobby your MP and ask him/her to present your objections in Parliament.
If you simply don't like the way the rules are applied at your particular airport then write to or meet to the security supervisor who trains the people at the gates.
Is this too difficult?. Are you supposedly intelligent people?
All of my life I have been dealing with people and applying compromises even when I felt that I was totally in the right. It is how people deal with life which sets them apart from other mammals.
At the end of the day the rules are there and if you comply with them to the letter as every other member of the travelling public ,me included unfortunately , has to do then you will have no reason to whinge. Get a life at least most of you are still in a job unlike some others whose firms have folded recently.
