W: What did you do at the office today?
M: I had a really busy day. I had to work a little overtime. In the morning an important client called to place a large order. I had to check some things with my colleagues before cortfirming the order.
W: What kind of things did you need to check?
M: (19) The most important thing was to check whether we had the goods in stock. If the goods are in stock, we can deliver them immediately. I also had to check the price. This customer is very important, so they get special prices.
W: I see. Did anything else happen?
M: I received a lot of emails from potential clients that I had to answer. Each time, I had to check files to see what we had agreed at earlier meetings. Each client has different conditions and requirements.
W: (20) It must be difficult to remember the details for each individual client.
M: Yes. (20) That’s why I have everything on computer files. I don’t use much paper at our office. After lunch, I had to deal with a complaint from a client.
W: I hate dealing with complaints. Was it a reasonable complaint?
M: Yes, it was. I managed to sort out the problem, but I was tied up with the matter for over an hour.
W: You certainly had a busy day.
M: That’s not all! (21) I also had to finish writing a sales report for my boss. In the end, I finished everything. I wonder what will be waiting for me tomorrow morning.
