Handling a handle or why does this happen to me???

At a cafeteria with a friend of mine at Odenplan in Stockholm. Suddenly I had to go and powder my nose. I walked to the ladies and opened the door and lclosed it behind me. Guess what happened? I suddenly stood there with the door handle in my hand... Now what could I do as I heard the door handle on the outside drop to the floor. That means that I am locked inside the loo...
OK so I could not use the toilet as I did not know if someone from the outside would be able to open the door. So I just stood there waiting for someone to show up. After about 5 minutes (felt like longer) a lady found the handle and opened the door and got frightened when she saw me in there. I said thank god you saved me. Please could we help each other. If I can do what I can here to do and if you watch outside the door I will do the same for you. It´s a deal!  So I eventually came back to my lonely friend. She wondered what took so long.....
