Korean in South Korea
Subways are clean and efficient. There is a timetable, but passengers can just go to the platform and check the arrival screens on the tracks. Tickets are available from both ticket vendors and machines. There are two types of tickets: single ride or multi-ride. The price of the ride depends upon the destination. When entering the track area, put the ticket through the ticket slot and then retain it because it is necessary to follow the same procedure to exit the subway at one's destination. If the ticket is single use, the machine will keep the ticket as the passenger exits; if, on the other hand, it is a multi-use ticket, the machine returns it until there is no more money on the pass.
