Who gives things to Atticus?

From the text:

Calpurnia said, “Tom Robinson’s daddy sent you along this chicken this morning. I fixed it.”
“You tell him I’m proud to get it—bet they don’t have chicken for breakfast at the White House. What are these?”
“Rolls,” said Calpurnia. “Estelle down at the hotel sent ‘em.”
Atticus looked up at her, puzzled, and she said, “You better step out here and see what’s in the kitchen, Mr. Finch.”
We followed him. The kitchen table was loaded with enough food to bury the family: hunks of salt pork, tomatoes, beans, even scuppernongs. Atticus grinned when he found a jar of pickled pigs’ knuckles. “Reckon Aunty’ll let me eat these in the diningroom?”

Calpurnia said, “This was all ‘round the back steps when I got here this morning. They—they ’preciate what you did, Mr. Finch. They—they aren’t oversteppin‘ themselves, are they?”
Atticus’s eyes filled with tears.
