I thought about that hook and eye, too, but I wondered if there may be some law about not being able to get someone out. eg- someone goes to the restroom, locks the door, has a heart attack, falls hitting her head, rendering her unconscious, and no one can get to the person to save her life because that type of lock cannot be unlocked from the outside. I have no idea if that is the case, but I could see it being so.
If that issue arizes give me and call and I'll pull the door open with my limp wrist. :roll:
