I took my blue ballpoint pen and wrote it small: Blink twice if you need me to call someone. I folded it up tight. When I packed her grocery bag, I slid that little scrap of paper right under the loaf of white bread, where her little boy’s hands wouldn’t find it.

She paid her bill. It was eleven dollars and forty cents. She gathered up the bags, her fingers red from the plastic handles, and she walked toward the exit. I held my breath. My hands were shaking as I scanned the next customer’s carton of eggs.

She reached the automatic sliding doors. She stopped right there, in that cold patch of morning light by the propane tanks. The glass doors kept hissing open and shut, open and shut, right against her shoulder. She had found the note. Her back went completely stiff.

I watched her from forty feet away. She turned around, very slowly, and looked right at me across the gray linoleum. She looked tiny. She looked like she was about to fall over. Then, she looked straight into my eyes. She blinked once. Then, slow and deliberate, she blinked again.

My stomach did a complete flip. My feet stopped hurting. I felt cold. She mouthed two words at me, her lips moving without a sound. “He is outside.” I looked through the big glass front windows. There was a black pickup truck parked crooked across two parking spaces.

A heavy man in a canvas coat was just stepping out of the driver’s side. He looked angry. He was walking toward the entrance with his head down, his hands shoved deep into his pockets. I didn’t think about the rules. I reached my hand under the counter of register four, feeling for the small metal bracket where the silent robbery button sits.

We are told to only touch it if someone has a gun. I pushed it anyway. I held it down until my finger turned white. Across the store, Reggie, our assistant manager, was stocking the laundry aisle. He is a retired Navy man, big and solid.

He saw my face, saw my posture, and he dropped a jug of detergent. He started walking toward the front doors, his boots heavy on the floor. The automatic doors slid open. The man from the truck walked in. He smelled like cold grease and old tobacco.

He didn’t look at Reggie, and he didn’t look at me. He just walked straight to Clara and grabbed her by the arm. “We are leaving,” he said. His voice was low, flat, and completely unbothered. He didn’t care that people were looking. In his head, he owned her, and he was just taking his property back.

“Let go of her,” I said. I came out from behind register four. My knees were trembling, but I stood right in front of the door sensor so the glass wouldn’t close. “Mind your own business, old lady,” he said. He didn’t even look angry.
