Ten whole minutes. Oh, the humanity!
I got trapped in an elevator around floor 14 in SF for about 4 hours one time. 4 on the elevator: me, a lady, a flaming F and THE STATE ELEVATOR INSPECTOR who could not believe it took 4 hours to determine we were stuck....seems all the communication devices were either ignored or did not work. They finally cranked us down as we were in a no exit portion of the ride. So, ten minutes in commie land does not sound extreme to me.
