Pizza delivery drivers have to deliver over 10 million pizzas a year. Any one of those deliveries could be cut short by a drunk driver that causes a head-on collision at 60 miles per hour. They don't have the luxury of foresight of knowing if they're coming home today or not. They know they're at risk. Contrast that with your average cop issuing citations and filling out paperwork and I'd say their job is incredibly fucking dangerous.
