The security staff is overly rigid and unfriendly. I was seized liquids (toilet products) despite the fact that they were all contained in vials not exceeding 50 cc., And despite the fact that together with my wife they did not exceed 1000 cc each (we had a single beauty case). They forced us to buy the transparent sachets even if they had already checked. The airport customer care service, to which we had reported the episode, proved to be totally useless as well as absent (non-response to several emails). Bad service and bad assistance in one of the most important airports in Germany.
