I have just come back from a visit to ATC and the ATCO's complain they are seeing far less of people than before - and here is why... I went and the car stopped at the security gate to go airside, it was underneath shoes checking, metal detectors, clear pockets, three forms to fill in triplicate, passport checked and cleared. Meanwhile I didn't even see it but security guards were doing a thorough search on my vehicle and found, god forbid, a bottle of water that I had in the car which was held until my return. Then there was the issue of the bottle of wine which had to be held back as well that I wanted to give the ATCO's as a thank you for a visit.. liquid... detained!
so it isn't the easiest start - now try bringing in say 12 students to show them around and repeat that 12 times, and by the time you have finished the form filling the shift that you wanted to see have changed over!
