New Yorkers, who live in the city that famously never sleeps, now can satisfy their desire for cupcakes in any of those endless waking hours.[19]A 24-hour vending machine that dispenses cupcakes opened for business this week on Manhattan’s Upper East Side, and locals are lining up despite the wintry temperatures for a taste.
    "It’s so fun," said Melissa Martelli, a schoolteacher and neighborhood resident as she ate a lemon sugar cupcake she bought from the machine. "You could just go in the store and wait on line, but it’s just so cool."
    Despite the Sprinkles cupcake store connected to the ATM, and the city’s abundance of all-night convenience stores, customers said the ATM has novelty appeal. "It’s the experience of buying a cupcake from an ATM. It’s an incredible concept," said Amy Benaderet, a financial services account manager who lives nearby. "You can get money at any time. Now you can get cupcakes at any time."
    At a price of $4.25 apiece, the cupcake choices include chocolate, coconut and lemon. "It’s cool, especially if you live around here and it’s like the middle of the night and you really want a cupcake. I would so do that," said Margarita Mazur, who works at a local tech company.
    But not every New Yorker has caught the sugar buzz. "I think it’s stupid," said Anthony Campagne, who was waiting while his tech company co-workers stood in line for their cupcakes. "It just doesn’t make sense. People don’t need cupcakes at three in the morning."
