Okay where did this start?
Years ago there were no fast food restaurants. But the corner Deli made doughnuts at the wee hours of the morning. Cops in Patrol units didn't have the time to stop and eat often. Just placed an order or had it set in front of you and up and at them you were.
Eat on shift ? Nah? Now you could get doughnuts and coffee to tide you over. This became a symbol of Cops without a call to respond to. Get two coffees and some Doughnuts to go. Eat in the car and so on. Many years later the Sergeant at the desk is a Sour-Puss. Why? Well after all those years of many missed meals filled in with the offending Round bread products and Who knows what Coffee formula, he's dealing with G.E.R.D and High Cholesterol!
Now the younger generation of Cops has Mickey "D's and " B " King " etc. Good Deep Fried food that settles where? The Middle. It's a daily fight for a cop to stay in shape.
Enter the night shift. In some towns the doughnut shops are the only ones open 24-7. The rest shut down at 10 and re-open at 7. So what's a pair of or single law enforcement officers to do? Hit the Donut shop. My take on this is this. Unless you enjoy missing meals because of some jerk ( Male or Female) causing problems that make you miss a meal or two as a daily thing, don't be a cop. Because when you hit the donut shop you get made fun off!
