Public Etiquette
People in need have seats reserved on Korean buses and subways. Allowing those who require these seats to use them is polite. This covers the old, the ill, the young, and the expectant. In contrast to the seats closest to the door, which are intended for pregnant women, the ends of subway carriages are for passengers in need. The reserved seats on Korean buses are frequently vividly colored. In Korea, exercise caution when eating and drinking outside.
In Korea, there aren't many public garbage cans, thus most people take their waste home with them. If you can't find a trash can, you shouldn't just leave your trash on the ground. If you can't find a trash can, you shouldn't just leave your trash on the ground. Since there are no trash cans on the mountain paths, this is true when hiking in Korea. Bring a little plastic bag for food waste as it is one of my top Korean hiking suggestions. This advice is applicable even outside of Korea.
Being cautious when utilizing public transportation is another crucial factor to take into account when eating and drinking. Eating and drinking on public transportation has recently been outlawed in Seoul. Although it's still legal, try to be considerate, stay away from stinky meals, and take your trash with you.
