strake,
Thanks for the headsup on that.
I'm a retired pilot and only fly as pax on LH about 3x year - try to use car on UK mainland rather than fly due probs as reported.
Only thing I can add is, when challenged by security, police, authority in general, don't argue; express regret and ask how to resolve problem.
i.e. do not open encounter, as did young Bas many years ago, to couple of plods, with: "WTF do YOU want?!"
(Note to Bas: Start taking your own advice.)
