Samuel is a taxi driver; he takes passengers to places they want to go.
He meets all kinds of passengers; Some are polite while others are rude, some are honest while others are dishonest.
Sometimes, he gives passengers the wrong change. Most of them will not return him the extra amount, but some honest passengers, after telling him that he has given them the wrong change, will return him the extra amount.
If he returns them less, most of them will inform him that he has given them the wrong change. Some passengers leave behind mobile phones and other things. Samuel will hand these over to the police, so that the things can be returned to the owners.
Samuel likes his job as a taxi driver because he likes to meet people and talk to them. He is proud of the fact that he knows, almost, all the areas in Singapore.
