Shhh! The Bus is Moving
In most major cities, a set of customs must be observed. There is a sure way to behave at work, in someone’s home, in a place of worship, and on public transportation. There are regulations to obey when using the public transportation system in South Korea.
On public transportation, silence is required. You are supposed to act as though you don’t exist. In most parts of the world, people aren’t fazed by others’ conversations or even performances on public transport. However, in South Korea, avoid speaking loudly and staring at others; no shows or phone calls are allowed.
