The whole of Europe is laughing at Britain, and that's okay
I wouldn't worry too much about that given the problems that AMS, CDG and FRA have had.
I do agree though that it has reached a point where something has to be done...and the same excuse can't be brought out EVERY time it snows. I get tired of hearing how "unique" Heathrow is with the complexities of snow clearing. It seems to be so unique that they can't figure out how to clear the place and keep it moving in the winter.
