LPT: When ordering at Starbucks, order with the most confusing order possible to watch other customers try to order their drink after you and have it rejected because the barista doesn't know what you ordered

Example: "I'll have a venti half-caf half-decaf iced caramel macchiato with extra foam, but only on the top half, except on Fridays, except when it's rainy, and except during leap years. Oh and can you please use 2 cups and drain it from one into the other, except for the caramel syrup, which you can add to the bottom cup first. Also, please don't stir it, because the cream and milk go on the top half, and I don't want it to get mixed up. And I'll pay with card, but only if the moon is in the 7th house and the Jupiter is aligned with Mars. If not, I'll only pay in cash."
