There are many examples that show how Atticus is probably not only the most respectful man in Maycomb but also the most respected. One of my favorites comes after the trial of Tom Robinson, when Tom's friends show their admiration for Atticus in true Southern culinary fashion.
The kitchen table was loaded with enough food to bury the family: hunks of salt pork, tomatoes, beans, even scuppernongs...
Calpurnia said, "... They 'preciate what you did, Mr. Finch. They--they aren't oversteppin' themselves, are they?"
Atticus no doubt " 'preciated" the food, but he knew that Tom's black friends couldn't afford this type of gratitude.
Atticus's eyes filled with tears. He did not speak for a moment. "Tell them I'm very grateful," he said. "Tell them--tell them they must never do this again. Times are too hard..."
Atticus is even respectful toward cranky, old Mrs. Dubose, who often refers to him as a "nigger-lover."
When the three of us came to her house, Atticus would sweep off his hat, wave gallantly to her and say, "Good evening, Mrs. Dubose. You look like a picture this evening."
I never heard Atticus say like a picture of what.
After Boo Radley comes to the children's rescue on Halloween night, Atticus respectfully acknowledges his deed.
When he got up and walked across the porch into the shadows, his youthful step had returned. Before he went into the house, he stopped in front of Boo Radley. "Thank you for my children, Arthur," he said.
