WC at the Airport

Out travelling again I have been once again reflecting about something that have annoyed me many times. Airport-toilettes. At every airport you repeatedly get reminded on not to "leave your luggage unattended at any time". But every now and then you might have to visit the airport facilities and encounter small tiny toilette booths where the door open INWARDS!! Not only is the booth small, 50% is covered by the closette, then the door takes the remaining 50% when you open it. So how the hell squeese in there with your luggage?? No woman can have come up with that design!
