Famous quotes containing the words service and/or features:

    “The ruin of the human heart is self-interest, which the American merchant calls self-service. We have become a self- service populace, and all our specious comforts—the automatic elevator, the escalator, the cafeteria—are depriving us of volition and moral and physical energy.”
    —Edward Dahlberg (1900–1977)

    “Each reader discovers for himself that, with respect to the simpler features of nature, succeeding poets have done little else than copy his similes.”
    —Henry David Thoreau (1817–1862)
