Doorstop as Security Device
Little rubber doorstops hide out behind hotel-room doors, waiting for fleeting moments of glory. And while the unassuming devices are put there so guests can prop open their doors, they're just as effective at keeping doors shut. So if you want an added level of security when you turn in for the night, wedge the doorstop under the bolted door. Voila, you've just added an additional lock.
