(I pick up the phone.)
Me: “Good afternoon, how may I help you?”
Caller: “Hi, can you tell me what 130 mm is in centimeters?”
Me: “13 cm.”
Caller: “Are you sure?”
Me: “Uh, pretty sure.”
Caller: “Hmm, okay. Thank you.”
(I hang up. 30 seconds later the phone rings again, this time one of my co-workers answers it.)
Co-Worker: “Good afternoon, how may I help you?”
*pause*
Co-Worker: “13 cm.”
