The most overused question at the moment: "How's your day been?"

I am so sick to death of  hearing:
"So, how's your day been?"
This hackneyed icebreaker thought up by some marketing guru/psychologist to keep the punters relaxed or to fill 'dead air' is well past its use-by-date. Salespeople, telephone operators, checkout staff have been using it for a few years, now it has filtered down to anyone. It's just lazy claptrap. Less is more.
Here endth my grumpy rant.
