Many years ago, I was the night manager, wrecker driver, night mechanic, etc. at a gas station. Three interstates came together, truck stop about 1/4 mile away. We attracted many people, as it was between Charlie Sherrill's area and Cajun's area, you may have read about the types that could come around.
The policy was that if a sheriff's car, highway patrol car, came by, their tires were checked, windshield washed, or something checked if they requested, and coffee was always on.
Amazing how having an LEO visibly around, and known to be around, kept things in order.
When I went on a wrecker call @ 2AM, and it looked even slightly off kilter, amazing how quick a deputy could be there to check things out, while I waited in wrecker truck, with the engine running!
Worked both ways, they got help when they needed it, amazing what you can see when pumping gas, or on a night wrecker call, and their presense helped me!
Good citizen and LEO cooperation managed to keep the bad guys somewhere else (well most of the time)!
