You HAVE to be learning

Never let yourself be stopped a second time by the same question. There is no excuse for any salesman being at a loss for a reply to any question put to him if he will take pains to understand his subject and avail himself of the training and suggestions and help which the sales department extends to him at all times. Let your argument be strong and unwavering on the point that a business man should see a thing for himself and fairly understand a proposition before he rejects it.
