answer: #Person1# recommends premium unleaded gas to #Person2# but #Person2# refuses because it's expensive. So #Person1# just gives #Person2# regular unleaded.
documents: #Person1#: What kind of gas does this car take?
  #Person2#: I don't know. It's a rental.
  #Person1#: I will give you premium unleaded. Alright?
  #Person2#: Sure, why not?
  #Person1#: That is the pump you are in front of.
  #Person2#: Is it expensive?
  #Person1#: It is the most expensive.
  #Person2#: Well, I don't want it then. Can I move to another pump?
  #Person1#: Yes, I can give you regular unleaded. But you have to back up the car a little.
  #Person2#: Give me regular unleaded then. I will back up. Can you wash my windows for me?
  #Person1#: I'm sorry, sir. This is not a full service gas station. I will help you fill the gas, but we don't wash windows here.
  #Person2#: Really? Well, I guess I have to get used to it.
