You might want to keep your fingers crossed if it's anything like Dublin! I heard that Aer Rianta have confiscated so many items deemed not suitable that they have little choice but to dispose of them. Apparently the numbers involved make it impractical to hold onto item(s) for reclaim. They do seemingly allow you to return to relatives/friends etc and give them the item to look after, and then allow you continue through security.
I am aware of people who have had items in bags - the usual nail clippers etc and have been asked to leave them behind. When asked if it was possible to collect the item(s) on return, the answer was a very definite no!
A way of life now - but probably for the better.
