It's a shame a bit of common sense if its already been swabbed.
You do have to bite your lip sometimes and I'm sure if you complained the whole process would suddenly take a whole lot longer!

Was something happening yesterday though?
Security alert??
I came through Abz yesterday after lunch and had to take my shoes off for the first time in ages. The metal detector was more sensitive than usual and the pat down was most thorough!!
In addition a Police presence in the security area.
