Korean people consider it as their table manners to make the youngers have a meal when the elders start dining.
When he or she has a meal with a guest, the host or hostess offers tasty and special food to the guest so that the guest can enjoy the meal. The host or hostess creates a harmonious atmosphere to have his or her guest feel at home and refrains from putting spoon and chopsticks down before the guest so as to make the latter have a meal enough.
