You got out in the hallway. There didn't seem to be anyone there.
As the door to the bathroom closes behind you, you feel a dagger on your throat, and my breathing down your neck. "You have touched my hat." I say calmly in your ear. "and now you shall feel regret."
I grab your arm and twist it behind your back, and take my hat back and place it on my own head, where it belongs. I hold your arm against your back and put my knife back to your throat.
