Perhaps I have the job title wrong - I mean the people that check your hand luggage to make sure there's no contraband.
I can understand scanning for knives/guns. Though from reading Jack Reacher I think ceramic weapons are a thing and won't set off the beeper?
But to have so many people wait for so long while customs checks the half centimetre of warm water that lies forgotten in a bottle. Or re-scans the lip balm in a hand bag (not a liquid, a solid!) Or the last little inch of nappy cream in a banjaxed tube.
What's the point?? Are these things genuinely potentially dangerous (or could dangerous things be disguised thus)?
How many attempts have airport security fended off in the last 20+ years?
I would love to know if it's a massive waste of time or if there have been more terrorist attempts that the general public are blissfully unaware of....
