Parked in sainsburys p&c space this morning, loading my shopping into boot when another car parks alongside me with a toddler, around 18 months / 2 years in back seat completely unrestrained. Not even a car seat in the car, not even an adult seatbelt round the child. Hoicked my judgy pants, finished loading my shopping, drove out of my space then started thinking, if they've not even bothered to get a car seat for the child, what else don't they do? Child had been left in car with a woman while two other adults went into shop. So I rang the police non emergency number. Waited a few mins, police turned up. Now I'm wondering if I was OTT? Should I have spoken to them myself? Not involved the police? Not sure whether to feel proud or silly? Was IBU?
