Are there any interesting or thoughtful details in the movie Green Book?

Talk about the psychological art of words. Before Tony had an interview with the doctor, the doctor had inquired about Tony and wanted him to be a private driver. Because of uncertainty, he called more drivers for an interview. Its embodiment is that the previous interviewer didn't decide on the spot, but he could decide the driver when he arrived in Tony. The doctor was worried that Tony would not follow him because of black people or Tony's family, so the doctor had this interesting conversation. In addition to paying a higher salary, the doctor also wants the driver to be a personal assistant and waiter, so that Tony can wash clothes and shine shoes. Tony wouldn't do that, so he turned and left. The doctor stopped Tony and praised his ability. Tony thought about it, felt affirmed, made a further counter-offer and finally reached an agreement. In fact, the doctor only asked Tony to handle things as planned as an assistant, and did not intend to let Tony be a waiter. In order to bargain, Tony made some unacceptable conditions. Let Tony have this condition to refuse objection, and let Tony's psychological acceptance threshold be lower. If the doctor directly asks Tony to be the driver's assistant, Tony may only accept driving regardless of the itinerary, or even refuse to drive for the doctor.
