Those are the purposes of the Wal-Mart greeters. Waiting time is the most important factor in customer satisfaction. Because customers are more pressed for time than ever before, standing in a checkout line beyond 90 seconds is considered a long wait. Men move faster through store aisles, spend less time looking and will not ask questions. They are more suggestible.
Women look at price tags and study the product packaging in the store.
A woman with a man will spend the least time there. He writes at length about its most important components. Because the customer is always in motion, signs must be attention-getting, clear and readable, relate information bit by bit, and interrupt natural sightlines. That means the products with the highest sales will be located at eye level and a little to the right when the customer faces the shelf. Display bins are better for that than shelves.
