The smell of a mouthwatering meal is hard to ignore — especially when it belongs to someone else. At least that's the suggestion of a recent study that found nearly 30% of drivers are snacking from the food they're responsible for delivering.

The survey conducted by US Foods, which supplies food to restaurants, gathered information from about 500 food delivery drivers and more than 1,500 customers in America who order through apps such as DoorDash, Postmates, Grubhub and UberEats.

Of the drivers surveyed, 54% admitted to being tempted by the smell of a customer's food, and about half of those people actually took a bite.
