It was early morning at the Sunny Café. Emma, the barista, was ready to make coffee when she saw something strange. She looked at the sugar jar and it smelled funny. "This is not sugar," she said to herself.

A customer, Tom, was sitting near the counter. He loved chemistry and heard Emma's words. "Maybe someone put the cleaner in the sugar jar by mistake," he said. Emma nodded. They checked the kitchen carefully together.

They found an open bottle of cleaner next to the sugar jars. It was easy to mix them up because the bottles looked the same. "We need new labels," Emma said, smiling.

With Tom's help, the kitchen was safe again. Emma thanked him, and they laughed. The café was ready for customers, and the coffee was perfect that day.
