“Hello, can I speak to [x] please?”
My favorite phone interaction with a marketing droid:
MD: “Hello, can I speak to Mr. Knox please?”
ME: "Sure."
...5 seconds of dead air later...
MD: “Hello, can I speak to Mr. Knox please?”
ME: "Okay."
...another 5 seconds later...
MD: "...are YOU Mr. Knox...?"
ME: "VERY good! Goodbye!"
