Imagine that you have a high-paying job at an important law firm in town. After a meeting across town, you decide that you would rather walk back to the office than take a cab. Taking a cab costs roughly $20 and would have you back at the office in 10 minutes. The walk takes 70 minutes. When you get back to the office, your boss chews you out and says that your decision was not ratibnal. You argue that by not taking a cab you saved the firm money. Who is likely correct in this argument and why?
