text: Kate: Marsha, could you pick up the child from the nursery? 
  Marsha: Sure, I can
  Kate: We'll pay for the taxi of course
  Tommy: But could you take Uber? it's more reasonable
  Marsha: I don't know how to use it
  Tommy: find an app in your store (apple or android) called "uber", register, it's super easy
  Kate: But does Marsha have a credit card?
  Marsha: No, I don't
  Tommy: 21st century and there are people without credit cards?!
  Kate: Tommy, please 
  Kate: We will pay a regular taxi, don't worry Marsha
  Marsha: ok!
target: Marsha will pick up he child from the nursery in a taxi and Kate will pay her back. Marsha doesn't have a credit card so cannot use Uber. Tommy finds it strange.
