 William F. Wyatt Jr. of the Chicago Tribune wrote that " have a nice day " used to be new and " fill [ ed ] a needed slot " . " Goodbye " , he stated , inappropriately indicates that salespeople are intimate with customers they do not know and would seem forced . " Farewell " , Wyatt said , would feel abnormal and could only be employed in an ironic context . The close of a transaction needed an oral ending . " Have a nice day " was the apt phrase for those who serve people they do not know to end a transaction .
