National Donut Day! The brief history of the "Cops&Donuts" stereotype: This stems from the 60’s and 70’s before our 24-hour society. Donut shops were the only business open for night shift working officers. It was a warm place to sit and write a report, or get a cup of coffee. Several officers might stop in throughout the night, giving officers a stereotype. Some 45 years later, and the stigma still remains. These were the days when convenience stores weren't open all night. Remember, 7Eleven was only open guessed it, 7a-11p. Donut shops were the only place a midnight shift worker could get a good cup of joe. This is why Police Officers are loyal to the ole' donut shop.
