I was at a very big market (international) this morning and as I exited the lunch room to retrieve my cart, saw a very young child alone in a cart with no one around. I stood there not moving for several minutes wondering where a parent might be. I could not even see a person in front or back of him that seemed to be paying attention to this child (probably around 3 or 4 years of age). The serving line in front does have glass so I could see the people buying their lunches. Finally I noticed a man that was looking around frequently at the child and finally he got through the line and came and picked the child up. I approached him to say how it is so easy for a person to snatch his child (John Walsh's on AMW had his young child snatched and killed in similar, only taking a second) and this man looked annoyed and said thank you for your thoughts and hurried away. Clearly child endangerment here but would you have said anything or just let it go?
