If you ever worked in sales or retail, you have a way to initially relate. I usually start to coach girls who work in sales, give some really useful advice. Get them to say, "Oh yeah, I never thought of it that way" or whatever.
As you do this, you make the "trust sale." They trust you, they listen to you, they laugh at what you say, they say "yes" when you suggest getting together. It's easy.
Order a copy of our sales book, Retail Selling Made Easy, which is a pro-active, no-pressure guide to selling. With that fun to read, easy book, you will have all of the info you need to hook a retail girl.
