Look there, in between the Oreos and the Pringles, it's...an automatic teller machine!
The basic idea here is great: there are a million bodegas in New York that would like to have ATMs inside their tiny spaces. But why build all the cash-dispensing mechanics into the ATM when it's sitting right near a machine that already does this - the cash register. It works like a normal ATM but dispenses a receipt at the end which you give to the cashier who gives you cash. Supermarkets can afford to retool their registers, but small shops can't. It's a little unnerving trusting your ATM card to this thing (at one point the display read 'dialing', implying it had an actual modem inside), but when you need cash you're desperate.
