We all often have this experience when we go to the ATM to withdraw money. a atm has no money. You have to insert a card and enter a password. Once you see no money, you have to queue up at the ATM next to it, but the same thing keeps happening in the future. Everyone wants to try this machine and then come to the queue as disappointed as you are.
So why don't I design a cash box with no money on the top of the ATM? The best way to keep flashing.
