This was last week. I took the picture because by this time, both individuals had done at least four different transactions and were holding a long line of cars behind them.
Besides being impolite as hell, the absolute lack of awareness was impressive. Not once they bothered to look around to check for possible dangers. Please get the idea that if the ATM tells you three times in a row you do not have funds, it is probably not an issue with your card and that about the only way you can fix it is to find a spot, park your car, get out and go inside the bank.
There are only two transactions to be done at the ATM (if you have any brains): Deposit and Fast Withdraw. The rest of inquiries, transfers and what–nots can be done at home with your computer or smart phone app.
Be both polite and smart.
