Pavlov Gone Horribly Wrong: Three Bells at ATM

Three Bells at ATM
Originally uploaded by stevegarfield

In the lobby of the Bank of America all you hear is constant ringing of the bells. Bells are ringing all the time but don't always indicate that an action needs to be taken by the ATM customer.

In this example, the light starts flashing and then the bells starts ringing, but the paper receipt only comes out on the third bell ring.

If the Bank of America wants to train us to do some activity at the sound of a bell, they need to reinforce that activity by dispensing a receipt when the bell rings and should not just start ringing the bell early.

Thanks Clinton for the revised title
