Nella Braddy Henney, The Book of Business Etiquette
“ And the salesman went.Salesmanship is service, and the man who persuades another to buy something he knows he does not want, does not need, and cannot use, is a scoundrel. “Good salesmanship,” and this is the only sort that any self-respecting man will engage in, “is selling goods that won't come back to customers that will.” It is cumulative in its effect, and the man who sells another something that really fills a want wins his eternal gratitude and friendship. ”
