High Quality Content by WIKIPEDIA articles! Have a nice day is a commonly spoken valediction, typically uttered by service employees to customers at the end of a transaction, particularly in Israel and the United States. Its repetitious and dutifully polite usage has resulted in the phrase developing a cultural connotation among some listeners as representing impersonality, lack of interest, passive–aggressive behavior, or sarcasm. The phrase is generally not used in Europe. Many European commentators have stated that it seems artificial or even offensive. Critics of the phrase characterize it as an imperative, obligating the listener to have a nice day. Other critics argue that it is a parting platitude and a trite space-filler used to prevent embarrassing silences. While defenders of the phrase agree that "have a nice day" is usually insincere, some consider the phrase to be comforting, in that it improves interactions among people. Others favor the phrase because it does not require a response.
