Greeting with "swaddee".

Pasa Thai has many words to greet each other for example; "Arun swad" for "Good morning", "Sah-yan swad" for "Good evening", and "Rah-tree swad" for "Good night". But normally Thai people simply say "Swaddee krab or Swaddee kah" in any occasions. However, it is not uncommon to hear those redundant words on television or radio.
