I would not normally expect to get away with it, but our security folks don't care; you can't get onto our floor without a badge or PIN, and we are a young enough startup that everyone still recognizes each other. The managers of the coworking space do not care what we do with the office suite we rent from them, and building security does not care what the coworking space does with its interior doors so long as the fire doors stay shut. The security folks at the head office of the coworking chain might care, as they're the ones operating the PIN lock we are bypassing, but they're not here to express an opinion.

Meanwhile, the phone rooms, bathrooms, printer, and most of the conference rooms are located outside our suite in the coworking space, so we'd all be punching in our eight-digit PINs half a dozen times a day getting back into our office if we didn't prop its door open.
