Famous quotes containing the word service:
“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)
