Which bus would the man like to take tomorrow morning?

M: Anna, come in, please.
W: Yes, Mr. Green. What would you like me to do?
M: I need a bus ticket to Seattle.
W: What time do you want to leave, Mr. Green?
M: Well, tomorrow morning, as early as I can. I have an appointment before noon.
W: There’s a bus every thirty minutes starting at 5:30 a.m.
M: In that ease, I’d like to leave then. Wait…My wife’s going to drop me off here on her way to work. Could you book me a 6:30 ticket instead?
W: Sure. Will it be one way or round-trip?
M: Oh, I probably should buy a round-trip ticket now, since I’ll be coming back tomorrow evening. Oh, is there a bus around 6?
W: Yes, there’s one at 5:45.  You’d get back before 8 o’clock?
M: OK, I’ll take that one. I told my wife we’d see a movie at 9:30.
