Has Zero Confidence In Them

(My dad answers the phone to a telemarketer.)

Telemarketer: “Hello, Mr [Our Surname]. I’m calling from [Car Insurance Company] and I bet I can save you £100 on your car insurance.”

Dad: “I bet you can’t.”

Telemarketer: “I bet I can, sir.”

Dad: “No, I really bet you can’t.”

Telemarketer: “I’m so confident I can, sir.”

Dad: “In that case, you owe me £100.”

Telemarketer: “What?”

Dad: “Well, I don’t have a car, so I have no car insurance. Therefore you owe me £100.”

Telemarketer: “That’s not how this works, sir.”

Dad: “We made a bet. Zero minus 100 is -100, so you owe me £100. Please make the cheque payable to [Dad’s Name]. Thank you!” *click*

(Dad does indeed have a car, and a very good price on his car insurance. Needless to say, we never had a call from this company again!)
