katze the cab driver , blue suit crumpled from a hard day 's work , sleeves rolled up and over his elbows , white shirt grubby , sweat-stained from driving , tie tugged down from his unbuttoned collar cap shoved back on his greasy black hair cigarette glued to his dry lower lip chin unshaven eyes red-rimmed and tired through overwork leaning against a chest of drawers with all the world weariness of a man who has been on the road for most of the day and not stopped to draw breath or drink tea or pause for even a moment in the endless quest to fuel his tank .
