It was a bright and sunny day when Sarah and her friend, John, decided to have lunch at a nearby restaurant. They sat down at a table by the window and looked at the menu. Sarah ordered a delicious sandwich, while John chose a big, steaming bowl of soup. They talked and laughed while enjoying their meal. When they finished, it was time to pay the bill. Sarah raised her hand to get the waiter's attention and said, "Excuse me, sir. Can we have the bill, please?" The friendly waiter smiled and nodded. He brought the bill to their table. Sarah checked the total and gave some money to the waiter. She said, "Here's the money for our meal. Keep the change."
