Human: Generate for me a description of a secret scene inside a bank with tellers and teller windows. Assistant: 
Whatever this area might have once been, it has long since converted to service the teller windows of the city's bank. A stout-looking stone wall has been put up and left unstuccoed to separate the tellers from any harm. All discussion on any transactions takes place through cast iron screens to ensure the security of the tellers and the bank's deposits.
