"Next" said the coffee & donut man (who I'll refer to as "Ralph") from his tiny silver shop-on-wheels, one of many that dot Manhattan on weekday mornings. I stepped up to the window, ordered a glazed donut (75 cents), and when he handed it to me, handed a dollar bill back through the window. Ralph motioned to the pile of change scattered on the counter and hurried on to the next customer, yelling "Next" over my shoulder. I put the bill down and grabbed a quarter from the pile.

When an environment of trust is created, good things start happening.
