For God, Country, and Coca-Cola by Mark Pendergrast, 1999, Excerpts
Sugar and tea were initially considered exotic luxuries available only to the wealthy nobility in
Poverty-stricken factory workers learned to grab a quick meal away from home, using hot sweetened tea as a pick-me-up. Teatime, a new British ritual, was gradually assimilated into all aspects of daily life.
This should sound all too familiar. Like tea and sugar, Coca-Cola started life primarily as a medicine, though not strictly for the upper crust. Like sweetened tea, Coke contained caffeine and sugar, along with a tiny amount of cocaine for fifteen years or so. A Coke break quickly became the American equivalent of the British teatime, while advertising stressed the role of the “pause that refreshes” as an aid to industry.
