Good morning ; 안녕히 주무셨어요?(honorific) Did you sleep soundly? 잘 잤어요?(respectful) Did you sleep well? 잘 잤어?(casual) "Good afternoon/evening" doesn't exist in Korean. Hmm...as for 좋은 아침입니다, it's rarely used in daily conversation, I'd say. It's something you hear from TV or radio.

We don't tell them in a different way. Just one expression will be enough,which is "안녕하세요.", but for "good morning", '좋은(good)아침(morning) 입니다' is often used.
