Andy's parents are at work. They always ¹open their pet shop early on Saturday because people often ²buy pet food at the weekend. At the moment they ³are serving customers. There are some children in the shop. They ⁴are looking at the tropical fish. Children ⁵are coming to the shop but they don't fit. Explanation: * open: They *always* open suggests a habitual action, so the simple present is appropriate. * buy: People *often* buy suggests a general truth, so simple present is used. * are serving: *At the moment* signifies an action in progress, therefore present continuous. * are looking: The present continuous is used to describe an action happening at the time of speaking. * are coming: The present continuous is used here as it is something that is actively happening now.
