I'm serious, British customs seize half eaten Marmite jar due to potential use in hijacking an airplane.

Exactly what I was supposed to be able to do with my half empty 150g jar I don't know. Threaten to force feed the passengers and crew? The problem with that is half of them would come back for more.
Last weekend, I took a flight out of Stanstead, England to Holland. Due to the bonkers security we have these days, my carry-on bag was virtually empty.

Through the scanner it went and was duely picked up. Security took it out, asked whose bag it was and then proceeded to do a fingertip search of it's contents. Only there were no contents. Granted, the bag was a skateboard bag and had lots of compartments and pockets. Five minutes later, and I mean FIVE minutes later, the last pocket was searched.

Out comes the small, half eaten jar or Marmite. Blanks looks by all. "I can't believe I have searchedd an empty bag for five minutes and only found a jar of Marmite!". But was it a security threat? She didn't know and had to confer with her boss. I guess she loved Marmite and her boss did not, as my beloved jar of Marmite, which has travelled all over the world with me (seriously, Easter Island, Peru, the USA), was dutifully thrown in the bin.

This trip was Marmiteless :-(
