He talked to the customer so there wouldn't be an awkward silence between them while he was driving towards the airport, which requires good socializing skills. The cab driver even made the customer feel comfortable and welcomed though the customer was leaving. However, that made the customer would want to come back again rather than complaining how bad the customer service was.
