TOEIC ETS

Joanne Matos (11:45 A.M.) Tuyet and Jim, do you know where I can find that big signboard-the one that we usually post at the entrance to advertise when we're having a sale inside? Tuyet Nguyen (11:58 A.M.) I haven't seen it lately. Why? Joanne Matos (11:59 A.M.) I'm setting up for this afternoon's party under the tent out in the café courtyard, and I want to have seating information posted for people as they arrive. Tuyet Nguyen (12:01 P.M.) Jim likely has it. He usually sets things up for those sales. But I think he's gone for the day. Jim Thomas (12:02 P.M.) No, I'm not! I'm out making a delivery right now, but I'll be back soon. You can find the signboard in the alcove just inside our building's delivery entrance. Just put it back when you're done so that I can find it the next time I need it. Joanne Matos (12:04 P.M.) No problem. Thanks!
