The machines (switch on) at 7.30 a.m. every day and (turn off) at 5.30 p.m. The factory (lock) at 6.30 p.m. by our security guards and all the staff (check) before they go home. We don’t want our jam to disappear! Now as you can see, strawberry jam (make) here today. And over there the jars (put) into boxes by our team. Hartson’s jam (not/export) because this country buys everything we produce. It’s very important to keep our factory clean and hygienic so everything (wash) very carefully every night. Of course nobody (allow) to smoke anywhere in the factory. Now I think lunch (serve) in the canteen at the moment, so shall we go?
