My houseboy was here to do some housecleaning yesterday. He rode the elevator up to the attic to vacuum clean the vestibule. He didn't realize (or forgot) that the light in the cab goes out 20 seconds after the cab stops. He didn't know where the light switch in the room is, so he was fumbling around in the dark for several minutes. I finally had to bring the elevator down and go up and "rescue" him.
