When you've got a deity as powerful as the Lord Shani, who needs locks? (I mean, according to Wikipedia, when Shani opened his eyes as a baby for the very first time, the sun went into an eclipse.)
That's what the management of the United Commercial Bank in Shani Shinganapur, Maharashtra, India, thought when they opened the first lockless bank:
"We took note of the general belief and faith of the people. Ever since the most revered temple came into existence several years ago, the village has not witnessed a single crime. In fact, all houses in the entire village have no doors. We took the risk and started the lockless bank a week ago," a senior bank official said. [...]
Gadakh explained that, by and large, it is believed that because of Lord Shani's power, the village has not witnessed a single theft or robbery in the recent past. "People here fear that if there is a theft or robbery, then the culprit and their family have to bear the wrath of Lord Shani," he said.
Meanwhile, the cops aren't too happy:
... unhappy local cops said the branch has been started in violation of norms prescribed by the Centre. "In view of increasing bank robberies, the Centre has made it mandatory for all banks to provide state-of-the-art security. If a bank opens a lockless branch, it amounts to a breach of conditions. We will take it up with the DGP and RBI," a senior police official said.
