When the cashier rolled her eyes and made that rude gesture, I noticed my deaf dad's puzzled expression. It was like she thought he couldn't see her, but boy, was she wrong. Dad might not hear, but he's sharp as a tack when it comes to reading people. Watching him handle situations is always something special. After all these years, I knew better than to underestimate him. He took a deep breath, paused, and then did something that not only surprised the cashier but left everyone in the store watching with their jaws practically on the floor. What my dad did next was something no one saw coming and it left the cashier stunned.
