I was prevented from taking a small pair of moustache trimming scissors on a flight a few years ago. I asked if I could take a cigarette lighter and a can of hair spray. They said yes.
The bottom line is that I can take a flame thrower on a plane, but I can't trim my moustache at my destination.
Well, you can sleep better at night because you can no longer take lighters or matches onto the plane with you.
I'm waiting for them to ban pencils because they are sharp and could be used to stab stewardesses and pilots.
