Do you guys remember the "no liquids on through security" era? This was a couple of years ago, just before BOM started its internal airside renovation. I had a bottle of water purchased outside the airport as it was April and baking hot. I had the full intention of drinking as much as i could and chucking the rest away at the check point. I approached the x ray and shovedthe bottle deep inside my rucksack. Not surpringly it got picked for a hand search but the CISF officer searching only did a half hearted job and i managed to get a whole 500ml bottle through. There were no kiosks after security in those days and you would go straight onto the aircraft. As soon as i got to the holding pen, i got the bottle out and started to drink whilst there were other passengers staring in disbelief that my water bottle was not confiscated whilst theirs was.
