Providing detailed instructions is always recommended when placing a custom order to avoid any misunderstandings. Adding a picture or a sketch can be even better. But for one customer who ordered a custom cake from Costco, this approach led to a hilarious mistake.

A Reddit user shared a post via r/mildlyInfuriating, showing how the supermarket giant got their order completely wrong, despite the customer is clear about what they wanted. In fact, the customer may have been a little TOO clear, which led to a hilarious outcome.

“Costco will give you exactly what you know you didn’t need,” the post read.

The customer in question filled out all of the relevant fields on the cake order form and even provided a sketch of how the cake should look, making their request as clear as possible. The sketch included the instructions “no writing / no designs” and “only request red frosting on the perimeter for top/bottom.” To further ensure there was no confusion, the customer added a big cross and the word “none” in the cake design section of the order form.

The customer’s custom cake order was meant to be an easy task, as they provided detailed instructions, even including a sketch of how they wanted the cake to look. They requested no writing or designs on the cake and only red frosting around the perimeter of the top and bottom. To ensure the decorator understood their request, the customer also wrote “none” in the cake design section of the order form. However, things didn’t go as planned, and the customer received a white slab with a printed image of their diagram in the center, instead of the expected red outline.

The post about the order went viral on Reddit, with many people finding it hilarious while sympathizing with the customer’s predicament. Some users defended the decorator, saying they did their best to follow the instructions provided.

“The good news is they did read both pages of instructions,” one user said.

“Honestly, I’m pretty impressed by how close the drawing is to the figure you drew,” another person wrote.
