The order — a large flat white, extra shot, oat milk, no sugar — was delivered at the correct temperature, in the correct size, with the customer's name spelled the way they said it.
The patron reportedly stood at the collection end of the counter for several seconds, turning the cup, before conceding that it appeared to be theirs.
"I kept waiting for the bit where it's not right," they said. "There wasn't one."
The barista, reached for comment, said they had made the coffee that was ordered. Pressed for elaboration, they said there wasn't any.
The customer has since returned twice, both times ordering the same thing, both times receiving it.
