Input: Text: this happened a couple of weeks ago. i work as a cashier at a large retail chain. one night, this woman and her child come through my lane with some sandwich making stuff. her card kept getting declined and she became visibly flustered. i took out my card and offered to buy her groceries for her.

at this point she becomes very upset and insists that i don't purchase her items, saying over and over again that it's okay. then her daughter gets angry with her because they weren't buying the food. i'm rather shy and awkward so i really don't know how to handle the situation. i didn't want to go against her wishes and start a conflict. so i let her go, and she starts crying on the way out.

i still think about that woman sometimes, and i still regret not buying the food for her.
