My Pet Hate

I understand the need for security at airports and am quite happy to almost strip naked so all my things can be security scanned. I was even amused at the whole body scanners in USA (spending my working life seeing naked bodies means I have no objection to an x ray image of mine being viewed).
BUT..... cutlery is another matter completely!!!
Who in God's name decided that everyone has to try to use the most pathetic knife in the world to eat their food at airports and on airplanes?
Now that we can take scissors on board, as long as they are under 4 inches in length, I resent having to try to cut a baked potato with something that is about as sharp as my elbow!
