Police say she walked into the bank located inside a supermarket and handed the teller a note demanding cash and threatening to open fire if the teller didn't comply.
That's when the teller expressed her crime-fighting dubiousness and asked if the suspect was serious. Police say the woman left without ever showing a gun.
They say she is also a suspect in a robbery Tuesday at the Bank of Smithtown, also in Centereach, a Long Island town about 50 miles east of New York City.
