Samuel Blatchford, Pickard v. Pullman Southern Car Company…
“ If the company issued tickets to all passengers alike at the price charged to passengers traveling in third-class carriages, and then issued tickets at corresponding prices to those desiring to travel in a higher class of carriage, it could hardly be contended that duty would not be payable upon the prices paid for such second ticket. The passenger who is content to travel in a third-class or second-class carriage in the day might well desire to travel in a carriage of a higher class by night ”
