An unidentified Starbucks customer in St. Augustine, Florida, recently picked up his drink with the words, "Diabetes here I come" written on the coffee cup.
"That first word just automatically brought the picture of both sisters in my head," the Starbucks customer told WJAX.
The customer said he has two sisters who have Type 1 diabetes.
"Just the struggles they went through, some of the doctor appointments," the customer added.
The customer's drink, a 16-ounce white chocolate mocha, has 470 calories when made with 2 percent milk.
The customer's cup in the picture says the drink includes Classic Syrup, which is intended to sweeten "any coffee beverage, specialty drink or dessert," according to the Starbucks website.
The American Diabetes Association website states: "Being overweight does increase your risk for developing type 2 diabetes, and a diet high in calories from any source contributes to weight gain. Research has shown that drinking sugary drinks is linked to type 2 diabetes."
The heath association recommends people not drink "sugar-sweetened beverages to help prevent diabetes" such as "regular soda, fruit punch, fruit drinks, energy drinks, sports drinks, sweet tea other sugary drinks."
The heath website adds, "These will raise blood glucose and can provide several hundred calories in just one serving!"
In response to the cup-writing incident, the Starbucks store manager, Kent Miller, told WJAX, "No, this is something, we definitely don’t condone."
The Starbucks corporate headquarters said in an email to the news station: "We strive to provide an inclusive and positive experience for our customers, and we're disappointed to learn of this incident. We are working directly with the customer to apologize for his experience, and with our partners (employees) to ensure this does not happen again."
The customer wrote a note back on the same cup: "2 of my sisters are diabetic, so not funny."
"Seeing and knowing the struggle my sisters went through since third, fourth grade, it definitely struck a nerve," the customer added.
