They arrive after a precarious drive through afternoon traffic at the ATM and the simple man's cash card doesn't work. He tries it again, and it still does not work. He tries his credit card. It does not work. The machine says it is an invalid card.
Same thing happens.
Our simple man beats a frustrated hand upon the modern technological machine that won't give him his money for his poor wife's and children's bus tickets. He calls home to see if he has got the PIN number right. There is no answer.
