when my brother was doing the cop thing he went to subway and they gave him his meal for free he stopped going there for a while. when he went back a few weeks later they asked why he stopped eating there he said it was because he felt bad getting free food. They told him they would give him free food if he would eat there every night as a deterrent. they also used to give free food to CAP and JROTC cadets and adult members once again as a deterrent (the military uniform) Last i heard they ocassionally give free food and discounts to LEOs but not as much as they used to
