Starbucks has said sorry to a Florida man for serving him his mocha drink with an awkward message that read, “Diabetes Here I Come.”

The awkward joke turned into a disturbing message for the anonymous customer who expressed his disappointment in an interview with Florida’s Action News Jax. He said that he was served a grande white mocha at Starbucks in St. Augustine with the said message. He claimed that usually, the cups have customer’s names labelled on them.

However, the customer said he did not find the labelled message funny as his two sisters were already suffering from Type 1 diabetes and he knew the adverse effects of the disease. According to ABC 2 News, he knew the struggles his sisters went through and hence the message turned up to be quite painful and offensive for him. “That first word just automatically brought the picture of both sisters in my head, and I was taken aback,” the man said as quoted by Mashable. “Just the struggles they went through and all the doctor appointments they had.”

A Starbucks spokesman confirmed that the company has released a statement of apology to the customer.

“We strive to provide an inclusive and positive experience for our customers, and were disappointed to learn of this incident,” the company’s statement read. “We’ve since connected directly with the customer to apologise for his experience, and with our partners (employees) to ensure this does not happen again.”

The customer said that he did not order the drink personally. A man in his office is assigned the duty of picking up coffees and distributing them among employees. He also said that he went to return the coffee cup personally along with a note. “2 of my sisters are diabetic, so … not funny,” he wrote on the cup.

He specified that he did not seek an apology from the Starbucks barista, but he wanted the coffee company to assure him that it would never happen again.
