1. A regular stopped by one morning and noticed something peculiar on the counter—a small, handwritten sign reading ‘Free Coffee for Life if You Can Solve This Puzzle.’ Curiosity piqued, he picked it up and found himself staring at a simple riddle: ‘What has legs but never walks?’ The man scratched his head, pondering over the puzzle. After a moment, another customer—a delivery driver—chimed in with an answer: 'A table!' They both laughed, realizing they were just there for a cup of coffee. The sign remained, inviting more curious patrons each day.
