Indeed. Sometimes people forget that if you work at the Sears Tower, once you get to your office you are really only concerned with the contiguous floors that your company also leases. You really have no reason to go from 30 to 75 and then down to 47. Once you are at work, the elevators appear completely normal as your little world within the tower is confined to a specific bank of elevators.
