Gregory's Server@CiaraNi ...Now, me, already being deep in the system have only brought a phone to pay with and can't get cash out via a phone swipe uh oh. She checks the price and says "take it for free bring the money later". Yes to humanity!!!! Now she's made a perfect gamble there, either I don't come back and she's made someone's Christmas, or I come back with the money, plus a tip donation for the charity. A computer system would never say yes to this.
@EmmaBirkett Nice example of the kind of interactions we're removing from daily culture. 'Computer says no' versus 'Human using social judgment says 'yes, here's a way to do this by social agreement'.
