I may've used a bit of fuzzy wording... he doesn't work in the building, but when he leaves for work in the morning, he takes the elevator all the way down. When he comes home, he always only takes it up to the 7th floor, and walks up 3 flights of stairs (unless its a rainy day, or there are other people in the elevator, in which case he'll just go to the 10th floor).
