1 [00:00]: Yes, I'd like two tickets for the 12:15 Express train to Appen, please.
2 [00:05]: I'm sorry, sir, but that train's full.
3 [00:08]: The next express leaves at 1:00, or you could catch the local at 12:30.

5 [00:17]: I see. What's the price difference between them?
6 [00:20]: The local is $3 cheaper per ticket.
