Just send your handbag/ purse through and leave everything in it apart from electronics like iPad or lap top and remove liquids.
They may search it, they may not, they may also scan for explosives. As my handbag is generally very messy, with a lot of coins and pens at the bottom, it gets searched most times ( I really should tidy it up lol). It's no big deal.
Takes five mins, they ask first, do their job and hand it back to you, usually, for me, with a funny comment about the mess inside.
Don't worry, they will tell you what to do, so you can't get it wrong, and just do as asked. I always try to maintain a sense of humour and let them do their job.
Sometimes it's not feasible though, I once had my luggage taken out ( i was travelling with hand luggage only and nothing was in the hold) and every item in my overnight case was individually scanned at Brussels, seemingly there was a small metal rod in my plastic hairbrush, which was the last thing they scanned, and it was very very busy at security.
I did lose my sense of humour when They had my underwear sitting individually on the conveyer belt for everyone to see, the same for every other item of clothing in my bag, they were all scanned one by one, but you just have to let them do what they need to do, no matter how ridiculous it appears.
That day it took them well over 40 mins to let me through, the woman operating the scanner was beyond adamant, even though the rest of the staff were as uncomfortable as i was, and the queue was held up substantially, with everyone staring at me and I found it very stressful as it was so bizarre, common sense would say if looking for a small metal rod shape, you scan the items that may contain it first, not the clothes and one by one. But that's what she wanted and that's what she did.
. However it's something I have never experienced before or since. Just do as asked, and you will be fine, and no matter how strange the request appears, just let them get on with it. Ultimately, it will be fine and you will soon be on your way.
