Security No liquids over a tiny volume, must be in container in stupid plastic bags if under that volume. ( How does that bag make a container safe when it is unsafe it not in the bag?)
Airside retail Any volume of liquids packed in any size of bottle, crated and taken airside via a cursory check by the same bottom-feeders who man the human security channels, no thorough check on contents (any check at all?) and then sold to compulsorily liquid-less passengers, aircrew and ground staff at extortionate prices.
Passengers and crew can then take these large, more or less unchecked containers on to the aircraft, as many as they can stagger on board with. So can all airside ground-staff with a reason for going into the cabin, ie cleaners, dispatchers, station staff etc etc.
All in the name of windfall profits for retailer's and airport owner's shareholders? How cosy, and how ineffective against terrorists.
