Feldman kept copious notes on bagel sales data and some of his conclusions are fascinating. For example...

* When the weather is pleasant ... people pay at a higher rate.
* When the weather is cold, rainy, windy ... payment declines sharply.
* During the holiday weeks of Christmas and Thanksgiving ... payment is lousy.
* But, during the holiday weeks of Labor Day and 4th of July ... payment is strong.

Because Feldman's bagel customers were office workers he was able to draw interesting conclusions about how workplace morale affects payment. The more sweeping conclusion was: The better workplace morale at a business, the greater the payment rates. And more interestingly, Feldman came to believe higher-paid executives cheated the bagel honesty system more than did workers lower on the corporate ladder.
