Always wondered why some of the CSRs at the call center would get chewed out more than others despite being polite and respectful and I think you just made me understand that it was because they sounded false. They had a very obvious “customer service” voice. The ones who didn’t tended to just sound like normal folk having a good day. (That’s the secret sauce, they usually weren’t having a good day, but they sounded like they were in on some joke with you, that joke being ‘ahh talking to people, am I right?’)
