In the movie Billy Liar, Walter Mitty is an automaton, of sorts, and simply goes along with the humdrum days that life chooses to throw at him. His daydreaming, an escape that he employs to make things less dull, outwardly shows forth in his work and his everyday life.

Hence, in the mailroom, he sits around doing nothing but daydreaming on the assembly line. The phrase that delineates his 'sinews spoiling' just adds to the colorful characterization.
