There are situations where you wouldn’t bother locking the bathroom door, like if you’re just ducking into your en suite . . . or if you live alone.
A random online poll asked people, “Do you lock your bathroom door?”
34% say they always lock the bathroom door . . . 32% say they lock it only if guests are over . . . 21% say they never lock it, even if guests are over . . . and 11% claim they don’t even shut the door.
Someone said, “My bathroom door doesn’t have a lock.” Others said that they leave the door open because their kids or PETS freak out if they don’t . . . and one person said they didn’t know bathroom doors besides public ones could lock.
