(I work in a store where we blend toppings in with the ice cream. The prices for addition “mix-ins” are posted in giant numbers.)

Customer: “Hi, I’ll have a small cake batter with Oreos, Heath Bar, M&Ms, fudge, and peanut butter sauce!”

Me: “Okay, coming up!”

(At the register.)

Me: “Okay, that’ll be $x.xx”

Customer: “What?! It says on your board that it is $3!”

Me: “Yes, but you got additional toppings, which increase the price.”

Customer: “Numbers aren’t real! Only scientologists believe in numbers! Why should I have to pay if I don’t believe in numbers?”
