[...] Leffingwell calculated that the placement of water fountains so that each clerk walked, on the average, a mere hundred feet for a drink would cause the clerical workers in one office to walk an aggregate of fifty thousand miles each year just to drink an adequate amount of water, with a corresponding loss of time for the employer. (This represents the walking time of a thousand clerks, each of whom walked only a few hundred yards a day.) The care with which arrangements are made to avoid this “waste” gives birth to the sedentary tradition which shackles the clerical worker as the factory worker is shackled—by placing everything within easy reach so that the clerk not only need not, but dare not, be too long away from the desk.
