user: There's four of us and we're leaving from Vegas.
assistant: Ok, where are you going and on what day?
user: We want to go to Fresno, CA on the 13th of March.
assistant: Ok. To confirm, you want 4 Economy tickets for the bus from Las Vegas to Fresno on March 13th at 11:30 am. Is that right?
user: Yes, that's good. What station does it leave from and which does it go to?
assistant: It goes from Union Plaza to Fresno Station. I'm getting some kind of error and can't seem to book those tickets. Should I try the one at 11:20 am? It's $36.
