Usually, it adds extra cheer to your day when the person who made your coffee beverage adds a decorative flourish to the cup, whether it’s traditional latte foam art or a pretty caramel drizzle. One Starbucks customer in Louisiana says that a barista served up two beverages adorned with a pentagram and the number 666 in caramel syrup.

Who drew these decorations, and why? What kind of Starbucks beverage are they? They appear to be cold beverage with clear plastic tops, so it’s they’re not regular foam-topped lattes. “I’m assuming those lids were used because we ordered no whipped cream and there was no need for a dome lid,” she later clarified.

At least the customer demanded to see a manager as soon as she received the drinks to make sure that the culprit was held responsible, right? Well, no. “I unfortunately can’t give the young man’s name who served it,” she posted to the Starbucks Facebook wall, “because I was so appalled that I could not bring myself to look at him.” She wasn’t too appalled or pressed for time to snap a picture of the drinks before consuming them, though.

A Starbucks representative told The Daily Advertiser that the company had apologized to her by social media, but they couldn’t identify the artist. “This obviously is not the type of experience we want to provide any of our customers, and is not representative of the customer service our partners provide to millions of customers every day,” Starbucks said in a more formal statement.

If you want an apology and for the employee who did something wrong to be corrected, you should call the problem to the attention of someone at Starbucks as soon as possible, picking up the phone if you didn’t check your takeout order before leaving. The customer says that she did file an official complaint other than her Facebook post, so there’s that.

Update: I am ashamed that I didn’t think of the “you’re in Carcosa now” joke first. Well played, Kelly Faircloth of Jezebel.
