Charged Five Hundred for Sow Delivery, Plague Made Her Regret

I went out to the countryside to deliver a big farmer's sow, and the sow gave birth to eighteen piglets without a hitch. The owner insisted the piglets' coats looked off, claimed I'd used the wrong medicine and ruined their quality. Not only did she refuse to pay my fee, she turned it around and demanded I pay her five hundred for the sow's nutrition costs. I gave a cold laugh, picked up my medicine box, and walked out. Three days later, a terrifying outbreak of swine fever hit the neighboring village, and for ten miles around, I was the only one who could mix the cure.
