As a person,
So that I can use a bike,
I'd like a docking station to release a bike.
As a person,
So that I can use a good bike,
I'd like to see if a bike is working
As a member of the public
So I can return bikes I've hired
I want to dock my bike at the docking station
As a member of the public
So I can decide whether to use the docking station
I want to see a bike that has been docked
As a member of the public,
So that I am not confused and charged unnecessarily,
I'd like docking stations not to release bikes when there are none available.
As a maintainer of the system,
So that I can control the distribution of bikes,
I'd like docking stations not to accept more bikes than their capacity.
