# req-003

As a user, given I have a beer bucket and pipes which express how much I want to
spend on beer, I want how much money is in my beer bucket to influence how much
I spend on beer, so that having buckets and pipes which express how I want to
distribute, and have previously distributed, my incomings and outgoings enables
me to control my spending.
