The only thing worse than a Starbucks barista getting your order wrong is a Starbucks barista judging your drink of choice. According to USA Today, a customer in Florida got something he never asked for with his grande white mocha: an incredibly rude note that reads, “Diabetes here I come,” in all capital letters.

The unidentified man told Mashable that he is quite upset over the note. “That first word just automatically brought the picture of both sisters in my head, and I was taken aback.” Two of his sisters have Type 1 diabetes. The drink was picked up by a co-worker, who brought the coffee order back to the office. After seeing the note, the man went to the Starbucks location himself.

He wrote “2 of my sisters are diabetic, so … not funny” on the cup before returning it to the store. He says he was not seeking an apology, but rather a promise that no one there would do such a thing again. The store’s manager says that he is looking into the incident and a spokesperson for Starbucks tells Mashable that the chain is “disappointed” by the situation. “We are working directly with the customer to apologize for his experience, and with our partners (employees) to ensure this does not happen again.”

Not only was the note crass, but it was also unwarranted. As far as Starbucks drinks go, a grande white mocha clocks in at around 470 calories and 59 grams of sugar. While that is quite high, it’s nothing compared to a number of  otherStarbucks drinks. For example, a grande caramelized honey Frappuccino has 68 grams of sugar, and a 20-ounce serving of Starbucks Hot Mulled Fruit drink packs a whopping 99 grams of sugar into one cup. Plus, who can even begin to count the nutritional nightmares of one of these over-the-top Starbucks creations?
