医生??? He is a business man!!!

Surprised! If you were in America and asked a question like this.

医生?? No way! He is not only "医生", but a "business man" running his own business! Just like when you stop by a Auto shop for your car, they recommend this&that to your car, they are doing business with you and try to promote their sales! You should be confident with youself and follow your heart!
