By 1902, when Rural Free Delivery was made an official service, postal officials had begun to crack down on the carriers’ extracurricular activities. They successfully pushed for legislation that forbad carriers from soliciting business or carrying mail order parcels outside of the mail.
While cutting down on rural carriers’ other business opportunities was aimed at improving delivery speed, there were other factors at play that were not addressed by any legislation. For many, the RFD carrier was often the only regular visitor to their homes. In the early years of the service rural carriers found themselves being asked to help fix machines or take care of farm animals. Others opened mailboxes to find grocery lists and coins for buying the goods. The most common sights were coins or goods such as eggs or butter left alongside outgoing letters in mailboxes to pay for their postage. The latter was so common that carriers around the country pleaded with postmasters to ask patrons to purchase stamps directly from carriers and not leave scattered payments (of any kind) in their mailboxes.
