I and two of my friends are at a convenience store buying drinks. My friend’s drink is $2.73 including tax. He hands the cashier exactly $2.73. But the cashier doesn’t take it.
Friend: “Here you go.”
Cashier: “This isn’t enough.”
Friend: “What do you mean. You said it was $2.73 and I gave you $2.73 exactly.”
Cashier: “Exact change isn’t enough.”
Friend: “What the hell are you on about. I gave you the exact money. Why can’t I have this drink if I gave the exact change?”
Cashier: “Fine, I’ll cover it this time.”
Friend: confused face
Cashier: “Go. Before I change my mind about helping you.”
My friend was muttering about the cashier all the way back to his house.
