Travel Kettle

We wanted to buy a new, small travel kettle. There are travel kettles on sale at Heathrow airport, terminal 2 but they all have 3 pin plugs suitable for the UK. This seems very illogical as that is the one plug that is guaranteed not to work at your destination.

Never mind, I thought, I'll be able to buy one with a small two pin plug on my return. Sadly, Frankfurt airport didn't have any kettles at all.
