I am a little suprised at the attitude some of the FC have about us self loaders, I know most pax leave their brains at home and act like two year olds as soon as they enter the airport. However to shout at people who have asked what seemed like a reasonable question begs of bad manners and arrogance - if we are that bad then do not work with us.
But I am glad to see that there are some reasoned responses on here
In saying that even as a vff 100 + flights a year - even I cock up, trying to catch Virgin Nigeria in Lagos back to LGW the staff at the door managed to notice I was about to board the Jo Burg flight and sent me packing. So there is a good reason for the checks and they do work. Do not take it out on the staff they are just doing their job.
