This is the common practise of telling someone that an empty seat is available. Up Close Koreans may appear to be pushy but actually that is the way they display friendliness. They tend to stand close together when talking or walking, often even physically touching. Squeezing through a crowd or brushing against others on a busy sidewalk is considered normal behaviour. Visiting Koreans sit, eat and sleep on the floor, so shoes are always removed when entering a Korean home.
Bare feet can be offensive to old people, so wear socks or stockings when visiting families.
Just For Laughs Where people from other countries would apologise for making a blunder, Koreans often laugh or giggle to hide their embarrassment. The right way to do it in South Korea is to laugh along with them as this is tantamount to accepting their apology. Keep Your Smile to Yourself Koreans, especially those who are more traditional, regard excessive smiling as being too forward or eager. Smiles are generally reserved for personal encounters. Names In South Korea, it is rude to call people by their first names unless you have been long-time friends.
