Переведите правильно пожалуйста, в переводчике я тоже могу перевести.
Frank Burke got into his car and drove quickly down the street, away from the hospital. He’d just had words with one of the other doctors, he was furious. Old Dr. MacDonald knew that the Wilkins boy was Frank's patient. He had no business interfering, none at all. Frank accepted a lot of criticism from the older physician, but he drew line at this. Just because MacDonald was the oldest doctor at Mayfair Hospital, he thought he could do anything he wished: the younger men should think nothing of it. Anyone would think Dr. Burke was incapable of treating someone who had just caught cold!
The other doctors at Mayfair Hospital all had complaints about the older man. As one intern said. "He makes you feel you're trying to put something over on someone just because you want to be a doctor!"
Another thing. Dr. MacDonald's methods were extremely old-fashioned. He was, for example, quite unprofessional in his treatment of patients. It was true that he was very friendly toward them, but he spent too much time with each: other patients often had to wait hours to see him. His altitude towards the you physicians was that of an intelligent, superior being dealing with* lot of idiots. Well, if the facts were known, young Dr. Burke at it* probably had twice the medical education that MacDonald had at 64! Frank had attended one of the best medical schools in the country; it stood to reason that he would become an excellent physician. One day, when the opportunity arose to do so. he'd take a stand with Dr. MacDonald, come to the point, tell him exactly what he thought of him. In his present frame of mind, that would be easy!
Frank glanced down and saw that the speedometer registered forty-five miles an hour, ten miles over the speed limit on this zone. "Take it easy," he told himself. He was so much on edge thinking about Dr. MacDonald that he hadn’t realized he was driving so fast. It was lucky there were no policemen around at the moment. All he needed to be arrested for speeding while thinking about Dr. MacDonald! Maybe it would serve him right, but that would be the last straw!
