Berea Police say a 'short change' artist is scamming businesses.
Investigators say a woman went to a McDonalds on Monday and paid with a $50 bill.
Police say when she received her change, she switched a $20 bill with a $1 bill.
Investigators say the woman then told the cashier she had been given the wrong change.
She then asked for, and received, another $20 bill.
Police say the woman has done this in at least three other businesses.
Investigators say that she was driving a black Ford Ranger pickup.
