A client visited my company this morning. While I came into the meeting room, the client greeted me by saying "How are you!" I have been thinking that when people first meet, they should greet each other by saying "nice to meet you!" How should I respond to his greeting？ Should I follow my text book of high school, by saying "fine. How are you?", or something else?
Also, I don't know how to respond to the other greetings like "How are you doing?", "What's up?", etc., etc..
Could you help me out? Thanks a lot.
