The Honesty Experiment - A store with an honesty policy (leave the money for what you took, no cashier) wanted to know if people would be more responsible not if they were actually watched, but if they thought they were being watched. So each week they posted a picture above the register. One week it was a photo of eyes, the next week a photo of flowers, then eyes again, and so on, and they charted the money they made each week. The results? People pay almost 3 times as much when there is a photo of eyes looking at them! - via Neatorama — xstevemurphy

This reminds me directly of Clerks when Dante says, as he’s hiding behind the register with his girlfriend and change on the table for the customers, “People are honest when they think they’re being watched.”
