A proud parent ordered a cake for her son, Jacob, who was graduating summa cum laude, which is a really impressive thing. It means "with the highest distinction", so it's safe to say that Jacob is a smart guy. The people at Publix grocery stores? Maybe not so much.
Jacob's mom ordered the cake online and even made a note explaining what summa cum laude means. No matter, they were still given a cake with the word "cum" censored, which led to Jacob's mom having to explain the issue to friends and family, which must have been fun. "Well, grandma, the people at Publix seem to think we were referring to ejaculate...". Mortifying.
There's a screenshot of the order on the BBC story, and you can see that the Publix staff also ignored the request for navy blue instead of bright blue. Why bother the 'special instructions' box on the order form if it's going to be ignored?!
Publix apologized and gave the family a refund.
