Somebody I know has a shop that sells musical instruments.
He posted online that he had the following conversation on the phone today.
Shop owner: "Hello, this is [...] Music Store. How can I help you?"
Caller: "Hi, I am [...]. I'd like to buy my son a piano."
Shop owner: "Oh, that's great to hear. Is this his first piano?"
Short silence.
Caller: "No, this is his dad!"
