A Florida Starbucks customer is steamed up about a recent drink order he claims triggered painful family memories.

The man, who wishes to remain anonymous, told Action News JAX that he ordered a Grande White Mocha last week from a St. Augustine Starbucks.

When he received his beverage, a note that read “Diabetes Here I come” was typed on the side of the order. The customer says diabetes is no laughing matter.

"That first word just automatically brought the picture of both of my sisters to my head," said the customer, who says his two sisters suffer from type 1 diabetes.

"Seeing and knowing the struggle my sisters went through since third, fourth grade, it definitely struck a nerve.”

The customer shared a picture of his order with the station, who took it to store manager Kent Miller. Miller immediately denounced the message and said his store doesn’t condone that kind of behavior.

Starbucks has come under fire in the past for its sugary, calorie-laden drinks. A 16 oz. white mocha has 470 calories—more than a double cheeseburger from McDonald’s—but Miller says baristas should only be labeling beverages with the drink type and customer name.

The customer who received the diabetes note says he doesn’t need an apology from the coffee chain but does hope to prevent a similar incident from happening to other customers in the future. He did, however, leave a message for the barista who wrote the offensive note.

On the same cup he wrote, "2 of my sisters are diabetic, so ... not funny."

Starbucks said in a statement that it's still trying to offer that customer a direct apology and it's working to ensure the incident will not be repeated: “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.”
