Imagine a customer service agent who can do virtually no wrong. She typically answers questions in about three seconds, with an astonishing 94 percent accuracy rate. She puts callers at ease, offering them information about related issues without making them listen politely through an entire spiel or pressuring them to buy. She's unruffled by verbal abuse, but she'll tell an irate caller firmly but politely that certain language is not acceptable. As for her own language, she's fluent in English, Spanish -- and many other languages too.
