answer: #Person3# checks #Person1# and #Person2#'s tickets and finds they are on the wrong train. Their tickets are for the express train but it's a local train. They think it's fine and #Person3# waives their fees for this train.
documents: #Person1#: I will try. 
  #Person2#: Who is that man in the aisle? 
  #Person1#: Oh, he is coming to check tickets. We have to show him our tickets. 
  #Person3#: Tickets, please. You are on the wrong train, ladies. These tickets are for the express train. 
  #Person2#: The express train? 
  #Person3#: Yes. The train you are on is the local train. The local train stops at every station. 
  #Person2#: Oh, no! We want to get to Dorsett. Where are we going on this train? 
  #Person3#: You are going to Dorsett on this train too. But it will take longer. The express train goes straight to Dorsett without stopping. This train is the local train. It stops at every station. 
  #Person1#: When will we get to Dorsett then? 
  #Person3#: In about two hours. 
  #Person1#: That isn't bad. I don't mind at all. We are enjoying the view of the countryside. 
  #Person3#: It's alright this time. I won't make you buy two new tickets. I will just waive your fees as you are on the wrong train. But next time, please be sure you are on the right train.
  #Person2#: We will read the signs more carefully next time. Thank you.
