Karma??? If a bank teller gave you back too much change, would you return it?

Or if a cashier gave you back more change than you were due, would you let the teller or cashier know? Would you keep the money, or return it? What if a cashier neglected to ring up one of your items? Would you let them know, or not? Is it your good Karma if they make a mistake? Or, is it better Karma to be honest and square it?
