Anti-Airport-Bogus-Security Rant

I am so sick of the absolute moron behaviour in airports - here's today's (gatwick)
complaints
1. the whole re-sealable transparent plastic bag thing - there was never any evidence that the alleged attack woudl actually work, and so there's this bogus waste of time, but worse - why re-sealable - whats that about eh? so you go thru security and every now and then they pull someone out who has a few tubes of cream (face cream, toothpaste) and have failed to put it in a clear resealable plastic bag and they are sent bag and given the choice : bin it, or check it. why? why would the clear re-sealable bag make it safer? what a load of complete bogus tosh.
2. why do i need to show my boarding pass when buying a bottle of water in Boots? there aint any duty free out of euro flights any how and I wasnt gettign a duty free price it was thhe high street price, and they don't do a discount for non EU flights)
3. why do the currency exchange places still swipe credit cards, as well as asking me for my PIN? surely this is a massive potential identity theft opportunity? (e.g. set up a fake currency exchange place for a bit, mine a few credit card magstripe data +PIN, scaper and use).
4. so they're still asking most people to take their shoes off - but if I am wearing sandels (e.g. by preference or for vacation in sun), this means I have to walk over a public, extremely busy section of the airport floor in bare feet. What are the chances I catch some foot thing off someone (or they off me)? surely Health and Safety people ought to care about this?
5. Why do they still ask those stupid questions at check in ("are you carrying any weapons of mass destruction", "do you have any A level chemistry experiments in your bags", and "do you have 175 kilos of fertilizer in your pocket, or is that just the foot infection you got from your last trip"?)

as usual, none of this is actually going to do real security much service but it is causing more than just inconvenience.

Oh and smug americans can't laugh - their airport "security" stinks - I've been through US airports twice post 11/9 (sorry, that's the rational date order) and been asked by security staff to hold someone's coat while that person is searched.
