W: What do you need to know? I think it's a really great system.
M: First of all, where does it go?
W: The university shuttle bus goes all over campus. It does not leave the campus; if you want to travel off-campus, you'll need to take the city bus. But the university shuttle bus will get you from one class to the next, very efficiently.
M: And how much does it cost?
W: It's free, can you believe it? So you don't have to pay a cent to get all around the university campus.
M: That's really great. And how do I catch the shuttle bus?
W: Just look for one of the bright yellow shuttle bus signs, and go stand next to it. You can see the shuttle bus signs all over campus. A shuttle bus will come along approximately every five minutes, so you shouldn't have to wait long.
M: That all sounds good. Thanks for your help.
W: No problem.
