Arrival OK. Quickly off the plane and baggage re-claim time reasonable. On return some issues around the staff. Lady on bag drop desk very pleasant but security staff brusque and ill mannered. Appreciate that they have a job to do but shouting "laptop/I pod" randomly at passengers and waving hands does not make for a happy experience. So busy searching for the huge list of things being shouted at me (most of which I didn't have!) was then turned on my heel by a guard shouting "lady - belt!". Could see that older passengers and those with young children were getting a bit stressed. However we hadn't yet met the lady in duty free! On purchasing a gift we were asked if we had 20 cents. Whilst getting out purse/wallet to try and assist we were assailed with a raised voice and a snatched note when we could not apparently magic up the requested coin within 10 seconds. Beer on the terrace very expensive but some decent sandwiches in the shop next to Burger King which we enjoyed on the flight home. This airport used to be better than this. Have scored based on the airport overall - there is no category for staff!
