This is a 24-story building that houses the offices of several hundred people. As you know, of the nine elevators in this building, only two or three are usually working at one time. Therefore, it would be very helpful if you wouldn't get on the elevator at the eighth floor just to ride up to the ninth floor. There are two staircases in the building, and I would be happy to point you in their direction. I'm not exactly the poster-child for physical fitness, but even I can manage walking up a few flights of steps rather than getting on the elevator to travel one or two floors.
Also, if you're going to use one of the restrooms, please flush the damn toilet. Your mother doesn't work here.
