My dad is very kind, but this time, he knew he was being played. So, he agreed to finish the job. But he had a plan to teach these people a lesson.That night, Dad returned with his tools, smiling politely at the homeowners as if nothing was wrong. He finished the grouting, sealed the edges, and even polished the tiles until the bathroom looked like something out of a magazine.The homeowners clapped their hands together smugly. “Perfect. Now get out—we’ll wire you half the payment tomorrow.”
