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!
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.
