I worked in the Sears Tower for a few years. Coming in from the west side of the building, had to walk down a flight of stairs, take an elevator up around a few dozen floors, transfer up a floor via an escalator to get the next elevator to get to get to my final floor at about 40 floors. It was about 10 minutes from entering the building until I got to my desk sometimes. Stairs were not an option because you could only exit at ground floor. Previous job, we had elevators straight to most our floors, we occupied the upper floors of a 37 floor building. We also had a few around floor 10, to get to those, one had to go all the way to gound floor and then back up. Within a block, stairs were an option and id generally use the stairs for up to 3 floors.
