Hi, I have a problem. I booked a cab to pick up a friend of mine. He still hasn't arrived. I'm starting to get worried about him. Can you help me?
May I have your name, please?
Sure it is Angela. 
Could you provide your booking ID, please?
uh yeah, it
Could you provide your booking ID, please?
sorry it's id 387
His ride is on its way
But he's still not here. Is everything okay?
I am sorry, I don't quite understand what you mean. I am only able to help you check that status of your ride.
Oh okay do you by chance know when he might arrive? It's been hours since I booked the cab to pick him up.
He is about 4 minutes away
Oh okay. Thank you.
Is there anything else that I can do for you?
No thanks. 
Goodbye. Enjoy your ride!
