There used to be a coffee shop in my town. Every day they had a two-part secret phrase that would let you get drugs, but it sounded like an order. I think I activated it one time. “Can I please get a double-double with whip cream?” “Sure. How’s your dog Mittens?” “I have no dog?!” Later, the coffee shop shut down because they got caught drug trafficking. They would double cup the coffee orders that had the drugs, and put the drugs in between the paper cups.
