You Just Drank PP

(A lady and her husband walk into the store and order two medium coffees, one with milk, and one with double cream and double sugar. It is required that we mark the lid in order to determine whose beverage is whose, so I mark the drink with double cream and double sugar. Usually for this I write ‘dd’ on the lid. I put the drink on the counter, and the lady walks over to pick up her drink. She looks at the drink and asks me why I put two ‘p’s on the lid.)

Me: “Ma’am, those are ‘d’s. The drink is facing the opposite way”.

Her: “Why don’t you put the proper “D”s on the lid?”

Me: “I use that to indicate decaf coffee.”

Her:“But the ‘d’ is not a real letter anyway; learn to write properly next time.” *walks off in a huff*
