The scene: Luton Airport London (more or less London)
The time: 12 noon, 8th December
The cast: A kindly safety inspector, a hapless flyer

I watched while a very polite inspector pulled out of one man's hand luggage: four jars of Nutella, and two large plastic bottles of shampoo.

Inspector: These will have to stay here, sir.
Flyer (obviously an Eastern European, probably Russian): ??? What??? What??
Inspector: They can't go past security, sir. I will have to throw them out.
Flyer: Nuuuu. Is for children. (Pulls out wallet and shows pictures of three children).
Inspector: I am sorry, sir, but they will have to stay here.
Flyer: Nuuu. Is for children!!!

This went on for some time. The useful intelligence wasn't that the flyer had a total of about 4 litres of prohibited items, but that Nutella is officially a liquid!

Tell that to the makers, it might get them some sort of tax break.
