ไม่ได้นึกถึงอุโมงค์ลอดแม่น้ำเทมส์ เพราะนายคร้ามไม่ได้พูดสักคำเกี่ยวกับแม่น้ำ จึงนึกถึง underground แต่ก็แปลกใจว่าทำไมจะต้องจ่ายเงิน 1 เพ็นนีลงไปเดินด้วย
ก็เพราะเขาเก็บค่าผ่านประตู
คุณวิกกี้ อธิบายว่า
Pedestrian usageAlthough it was a triumph of civil engineering, the Thames Tunnel was not a financial success. It had cost a fortune to build—£454,000 to dig and another £180,000 to fit out—far exceeding its initial cost estimates. Proposals to extend the entrance to accommodate wheeled vehicles failed owing to cost, and it was only used by pedestrians. It became a major tourist attraction, attracting about two million people a year,
each paying a penny to pass through, and became the subject of popular songs. The American traveller William Allen Drew commented that "No one goes to London without visiting the Tunnel" and described it as the "eighth wonder of the world". When he saw it for himself in 1851, he pronounced himself "somewhat disappointed in it" but still left a vivid description of its interior, which was more like an underground marketplace than a transport artery.
