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. 
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.
