It is unnecessary to leave a tip for service in South Korea. A 10 per cent service charge is automatically added to bills in most hotels. Banks are open from 9.30am to 4.30pm on weekdays and until 1.30pm on Saturdays. Department stores are open seven days a week from about 10.30am until 7.30pm and most markets and shops keep longer hours. Seoul's Kimpo Airport is located approximately 18 kilometres from the city centre.
Taxis are expensive and in short supply.
Traffic jams are not uncommon. There are good airport buses which can be booked through hotels. Never give objects which come in a set of four, as this object has a death association in Korean culture. Red is the most suitable colour for wrapping paper in Korea. Blue is a lucky colour in South Korea and is a suitable colour for a gift or for wrapping paper.
