They cater to the two career families. How about home shopping channels or the Internet. Yes, this may mean fewer items sold in stores, but they have not replaced the hands-on shopping experience. This is not to say that men are shopping more. No, in spite of it all shopping is largely a female activity.
Men still shop, but men and women differ greatly in their styles of shopping.
Women are more conscientious than men. As an example observe a lady buying vegetables. She typically looks over each item carefully before choosing, while a man usually gives it a quick once over before adding it to the shopping cart. Another example is that pile of catalogs that you receive on a daily basis in your mailbox. Women demand more of a shopping environment.
