W: Excuse me. I've been waiting here for 15 mins. Do you know how often does No. 3 run?

M: Oh, it runs every 20 mins. You must have missed it, when you came here. It should be here any minute now.

W: It seems that you have got here at a good time. Do you have a bus schedule?

M: Yes, I do. You can go to the Transport Department to get yourself a bus schedule and a bus route map.

W: I see, thank you.
