I am a self professed sales geek. No way around it. If I see a great example of a shining star in the sales world whether it is someone who is selling radishes or rolls royces, I want to learn from the experience it! One of my observations as I travel helping people and companies have their greatest year ever is that most sales professionals will get their prospects to the 1 yard line and not ask them to buy. This is not true in New York City.
If you are buying a pair of jeans in NYC, the clerk will help you find the right pair (build rapport), ask you what you think about them (qualify) and close you. If it is too much or you start to walk out, they will negotiate! It amazes me how passionate someone can be about a pair of $40 jeans!
I purchased a pair when traveling there a while back, while the jeans are worn out; the lesson has remained. Don't forget to Ask, Ask, Ask!
