I have been through a few airports this week.
Here is the "standard security check" items I've endured:-
1. Jacket off, shoes off, computers out of bags, liquids out of bags, plus a body scan.
2. None of the above.
3. Jacket on, shoes on, computers out, liquids out, UMBRELLAS out (I kid you not - where the f*ck does it mention THAT in the security details?)
It drives you mad doesn't it?
