I continue to go through AMS frequently and I just don't recognise the rude security attitude mentioned above. They're certainly less rude than the TSA and than most English security. They are, perhaps, less likely to actively say things like "please, sir, may I search your bag" but that's not being rude. I have to wonder if that's the problem for some people, or if some passengers are just up-front un-cooperative and confrontational, or if they consider secondary search to be some sort of great affront to them.

AMS security is thorough, and is more fussy about keys and coins than most airport security. Even knowing this, my rate of secondary search there is higher than Heathrow - often simply because my set of laptop cables and accessories gets looked at. So knowing this, if you separate out into a separate tray the following, you will have an easier time: keys, wallets/purses with change, laptop chargers and cables, empty water bottle, and (computer) tablet keyboard as well as the usual liquids, things-that-look-like-liquids, (computer) tablets, and laptops.
