Thus, he demanded that the workers should work with a blunt drill whilst the other one was still sharpened. Yet, they refused by arguing that the [...] Thomp-son felt that this issue deserves some more of his attention, so he mumbled to the workers ‘Work on, and be more efficient’ and went back to his carriage to go home, thinking about this problem.
