Is He a Good Doctor?

An American visiting a remote area in South America became sick. “I have to see a doctor,” he told a local. “How can I know which doctor is a good one?”
“It's easy,” was the reply. “Every time a doctor loses a patient, it's our law that he must fly a balloon above his office.”
So the American began his search. One doctor flew 20 balloons, another 30. Finally the American found an office that was flying only five, and he went in.
“You will have to wait,” the doctor told him. “For someone who only started practice yesterday, I've been very busy.”
