In As I Lay Dying, what was Anse upset about paying for?

C. Addie's doctor visit

Making me pay for it. She was well and hale as ere a woman ever were, except for that road. Just laying down, resting herself in her own bed, asking naught of none. "Are you sick, Addie?" I said. "I am not sick," she said. "You lay you down and rest you," I said. "I knowed you are not sick. You're just tired. You lay you down and rest." "I am not sick," she said. "I will get up." "Lay still and rest," I said. 'You are just tired. You can get up tomorrow." And she was laying there, well and hale as ere a woman ever were, except for that road. "I never sent for you," I said. "I take you to witness I never sent for you." "I know you didn't," Peabody said. "I bound that. Where is she?"
