24. It was Sunday in New York City. He needed some cash. He walked to the ATMs in his nearby bank. Through the plate glass windows, he could see a woman using one of the ATMs. He pulled on the glass door. The door wouldn't open. He pulled again. How did she get in there, he wondered. She finished using the ATM. She walked toward him, opened the door, and stepped outside. He held onto the open door and walked inside. She must have waited for someone, too, he thought. He got his cash from the ATM and started to walk out. Just then a young woman walked in. Puzzled, he said, "Excuse me. How did you get in here? That door is locked." She said, "Outside, there's a slot next to the door. Just slide your ATM card into the slot. The door will unlock. How did you get in here?" 1.4
