Today I came home from another city. There are intercity high speed trains between the cities, and the tickets are in two classes: first class and second class. The fare for the first class seats is nearly as twice as much as the second class seats, because the first class seats are a little wider and more spacious than the second class ones. At first, I intended to buy a second class ticket, but they were booked up, so I had to buy a first class one.
