It was a bad night for Lewis. His research in the neighboring town has taken longer than he expected. It was late and he was very tired when he drove home. He turned into his building’s parking lot, but all the spaces were full. He drove back out onto the street, looking for a parking space. The first block was full. The next block was almost empty. Lewis didn’t see a "no parking" sign, but he has expected that his parking were allowed there. Most the spaces would be filled. Then he saw a small parking lot with two free spaces. He was so glad to see them that he didn’t even think to read the sign by the entrance. He drove in, parked and hurried home to go to bed. The next morning he went back to the lot to get his car. It was gone. He ran home and telephoned the city police to say that his car had been stolen. It took the police only a minute to tell him what had happened: his car had been on a private lot. It had been taken a way by the police. Lewis had to take a taxi to visit the city garage far from the city center. He had to pay a fee of 40 dollars to get his car back. In addition, he got a parking ticket, his first one ever in Greenville.
