Did you hear about the man who is trying to visit every company-owned Starbuck’s in the world? John Smith, a.k.a. “Winter,” is a 32-year-old man has been on his quest for 7 years and has visited 4,122 stores in North America, 114 in Britain, and 53 in Japan. Though Winter is doing well, his quest will keep him busy for some time, because Starbuck’s opens an average of ten new company-operated stores around the world each week.

Winter’s quest began in Plano Texas in 1997. When the topic of the chain’s growth came up, Winter says an idea randomly popped into his mind. “What would it be like to visit every Starbuck’s?” After attending a concert later that year, and visiting a few Starbuck’s along the way, Winter was hooked.

Winter’s self-imposed rules require him to drink coffee at each store, so he usually asks for half a cup. Though he sometimes gets tired of the taste of coffee, Winter says, Starbuck’s is his life. He adds, “There’s no way to be finished unless Starbuck’s goes out of business or changes its name. Those are two scenarios under which I would essentially be done. But there’s really no such thing. The best I can hope for is to keep up. I can’t foresee myself stopping. It’s too rewarding an experience.”
