Of Great Opening Words

I'm reading another great book at the moment called "Life's a Pitch - what we can learn from people in sales". The author gives a great example of good and bad questions sales people can ask on their way to a sale. Bad, for a sales person on a shop floor includes "Can I help you?" He argues that this is a bad question because it's a closed question and one that invites a No and a closed door. Much better to say "I see you're looking for a suit Sir. Is it dark or light suit that you're looking for?"
Try getting out of their grip then....
