hey assistant, can you call an Uber for me.
Sure boss, where are you going?
Im flying to New York today, so I need to go to the airport
yes, your flight is in 3 hours. are you at home?
yes, I'm going to DCA or IAD? I forget.
you are flying from DCA, so I will call an uber for you right now?
yeah, it take at least an hour going to DCA with traffic. Plus I like to have spare time
no problems, what kind of car?
it doesnt matter, which one is faster?
so there is Uber X or Uber Black and Uber pool. Uber Back is faster but more expensive, pool is the cheapest but you have to wait for at least 15 minutes for a car.
uber black or uber X, I don't want to do Uber Pool
okay, so Uber Black will cost $80 to the airport, and Uber X will cost $60. according to the Uber app wait time is about the same.
okay, then call me an Uber X.
okay. just a second. 
thank you.
and Uber X is 5 minutes away from your house.
okay, I'll be waiting outside of my house.
oh no, the Uber X just canceled, closest to you is an Uber Black, 5 minutes. other Uber X will be like 15 minutes.
oh well, Uber Black it is.
okay, your ride is on the way and that you can check status on your phone.
