How is the tow company supposed to know you are parked legally and within the rules of the apartment complex, after hours if your decal is on the floor of your car? Do you expect them to jimmy open the door, search all the areas of the car, and then if they still can't find it, tow the car? Maybe they shouldn't tow ANY car after office hours because there is no one to secondarily verify if a car is suppose to be there. Wait, that would negate the reason for them being there and the need for parking permits.
