Headbut
Ah Ten West, the trouble with the headbut technique, is that you might come accross someone like me, and I'm horrible and your headbut might result in serious injury, for you! just kidding, I'm a nice chap really.
Yes well the sale of alchohol at airports and on board is asking for trouble isnt it? but the businessmen would argue that banning it would lead to an increase in airfares, due to increased landing fees and this being passed on to the pax, thus leading to a reduction in the number of flyers and therefore job losses, the converse argument of course is that it would make flying a more pleasuable experience for others and therefore increase pax numbers.
Personally I believe, where you have large ammounts of alchohol in what for many is already a very stressful environment is beyond stupid, but hey what do I know!
