There are no security secrets in the UK. Judging by the treatment we receive, we are considered to be the greatest threats to aviation. We are cut no slack, have to comply with every pointless procedure and do as we are shouted at. So if you have a ticket, go through the departure lane used by passengers. You will soon be shouted at for something or other and be told you should have known better. And when you do the same an hour/week/month later, the rules will have changed. Just smile and wave.
