  #Person1#: Premium, PLS. Could you check my tyres, too? I think they need air.
  #Person2#: No problem, Madam. Should I check the air in the spare tyre as well?
  #Person1#: I don't think so. It's brand-new.
  #Person2#: Should I clean the windshield for you?
  #Person1#: Yes, PLS. I also need you to check the oil and the radiator.
  #Person2#: All right, Madam. It's ok. There is hardly any water in the radiator. It's dangerous, Madam. You could break down, because of the heat you know.
  #Person1#: Pls fill it up with water then.
  #Person2#: Anything you say, Madam.
  #Person1#: Do you take credit card?

  #Person2#: Thank you, Madam. Have a nice drive!
