Don’t Count On Intelligence

Customer: “How much is this? I’m kind of bad at math.”

Me: “Sure. It comes to $10.20.”

(The customer hands me a $10 bill.)

Customer: “Here you go.”

Me: “All right, I need at least twenty more cents.”

Customer: “Oh… all right.”

(The customer puts down five pennies.)

Customer: “Is that enough?”

Me: “Fifteen more cents.”

(The customer puts down a dime.)

Me: “All right, you have $10.15 now.”

(The customer puts down five more pennies, but takes away the $10 bill.)

Me: “All right, you have the right amount of change. But I need that $10 bill.”

Customer: “But this is twenty!”

Me: “Twenty cents. And your total is $10.20.”

Customer: “Oh, I get it.”

(The customer hands me a $1 bill.)

Me: “I’ll need that $10 bill you had before.”

(The customer gives me the $10 bill and begins to take away the 20 cents.)

Me: “Wait… actually, no, you’re good. That’s the right amount.”
