Sarah was at the grocery store, waiting in line at the checkout, when she noticed the person in front of her struggling to find their wallet. The cashier was patient, but the line was growing longer, and people were becoming restless. Sarah quickly offered to cover the small amount for the groceries. The person was incredibly grateful and promised to repay her. Sarah waved it off with a smile, saying it was no trouble at all. As she left the store, she felt a sense of warmth, knowing she had helped someone in a small but meaningful way.
