I'm beginning to think this is becoming a national sport amongst anybody working at airports. Professional Pilots must start countering this gathering trend. Seems to me a good way would be for pilots, before going through terminals, should dab some 'after shave' on. If you were to leave your after shave at home, it is not unreasonable to use a few dabs from a miniature bottle of Scotch/JD you may have (with receipt of course), being careful to avoid imbibing any of the prohibited liquor. Then let all the 'heroes' grind air traffic to halt whilst they wait to be declared 'clear'. A week of this will stop this nonsense. I say this as a teatotaler myself with no wish to encourage illegal drinking, but it is becoming a witch hunt to try and get a pilots scalp on your belt, and this is not healthy. Pilots should have the right to relax and enjoy their rests on nightstops when they can be on 6 earlies in a row with a couple of days off then another 6 days. This gives ONE day to have a drink in a fortnight. Something has to change- either rosters are stretched suitably or pilots can socialise without breaking laws, but this current witch hunt must stop.
