text: Josh: Our flight is delayed..
  Josh: They say that we might have to wait here even up to 5 hours
  Tom: oh, really?
  Tom: so you won't be here before midnight?
  Josh: I don't think so...
  Tom: hm.. there are no buses at night, I'm afraid. 
  Tom: you will have to get a cab.
  Josh: Is it very expensive?
  Tom: yeah, quite expensive...
  Tom: Actually, I'll call you a cab, once you arrive. 
  Tom: This will be a bit cheaper...
  Josh: and what about uber?
  Tom: uber will be far more expensive, trust me
  Josh: ok. I see. Thanks
  Tom: no problem. 
target: Josh's flight is delayed, so he won't arrive before midnight. Tom will call him a cab once he's landed, which is cheaper than Uber.
