In the tidy little town of Bellefontaine, Ohio, nestled among the quiet hills and brick-paved streets, Martha Dellinger ran the only pharmacy for twenty miles in any direction. At 67, Martha was as sharp as ever, though she occasionally joked that her glasses were doing more work these days than she was.
It was a Tuesday—rainy, unremarkable, and slow. The kind of day that lets you catch up on paperwork and drink your coffee before it gets cold. Martha had just filled a prescription for Mr. Raynor, the retired electrician who came in every two weeks like clockwork for his blood pressure medication. The label should have read “0.25 mg.” But somehow, her hand slipped on the keyboard. “2.5 mg.” A misplaced decimal. Ten times the dosage.
Mr. Raynor didn’t notice. He trusted Martha the way you trust an old friend. And Martha didn’t notice, not until the following morning, when she was going over her records. A quick rush of heat bloomed in her chest as she scanned the label. She called the Raynors immediately, but no one answered. She tried again. And again.
She finally drove over.
Mrs. Raynor answered the door, flustered and holding her phone. Mr. Raynor had collapsed early that morning, and the paramedics had just left. He was in the hospital, stabilized, but the doctors were still unsure what had caused the sudden drop in blood pressure.
Martha knew.
Later, at the hospital, she confessed the error. Tearfully. Plainly. The Raynors were shaken, but gracious. “We know it was an accident,” Mrs. Raynor said, though her voice trembled.
Martha reported the incident herself to the pharmacy board. She received a formal reprimand, but was allowed to continue working. Still, for months afterward, she double-checked everything she touched. Her staff noticed. Her customers noticed. And so did she.
From then on, a sign sat above her workstation in neat script: “A decimal is small—but so is a bullet.”
It was a quiet reminder in a quiet town, but it rang loud in her mind every day she opened her doors.
