On Monday, a 28-year-old went into a bank in New York and demanded $20,000. The teller shoved some money in a bag, and the man left. But when he looked in the bag, he realized the teller gave him LESS than he asked for . . . and he felt RIPPED OFF. So he went back to the bank to demand the rest of the money . . . WHILE the cops were there investigating the robbery. He was arrested.
