[Prudence]

Note to security officers:

If you want to keep people out of the elevator for a two-hour span so that your visiting dignitary doesn't have to rub elbows with the proletariat, or ride along with explosive devices, you might want to think of a better "out-of-order" reason than "preventative maintenance."

The state of elevator repair services on campus is widely known. Elevators regularly sit inoperable for weeks at a time waiting for their turn in the repair cycle. The idea that you would be so caught up suddenly as to be into a preventative maintenance cycle is laughable.

You're not fooling anyone, you know.
