Last time I heard 'have a nice day' was yesterday. Twice.
Girl in local town handing out cards, presumably on behalf of a solicitor, advertising compensation help. I absolutely hate the idea of suing for compensation after some little thing goes wrong, and I loathe with a greath LOATHING the sort of people who are capitalising on it. So I refused to take a card. "Have a nice day", said girl.
She obviously had a short memory, because half an hour later when I passed her again, she tried to give me a card and I told her why I didn't want it. "Have a nice day"...
