Few things get me more than hell-spawn abandonment. We were right next door to a bar so mummy, and daddy would often dump their crotch-fruit in our toy department and take off for the evening.
The worst one we had was a woman who dumped a disabled kid in a wheelchair she was supposedly baby sitting. We thought she was the mom at the time, but she was just a relative. Too bad we didn't have the contact number for the parents... I suspect they would have been very interested in a phone call from us.
The kid was very disabled: as in quadriplegic, can't move arms or legs at all. I heard the kid making noise, but they were semi-regulars and the kid always sort of makes groaning/wailing sounds so I didn't pay any attention for maybe 45+ minutes. All of a sudden I realize 1.) she is hidden in a blind spot from our cameras 2.) they haven't moved for quite some time.
I feel pretty awful I didn't notice this sooner, but kids making a lot of noise is sort of common where I used to work. Usually when nanny and disabled kid come in you can track their progress though the whole store.
This time the noise is coming from one location. So I go over and low and behold the kid is all alone. I quickly get the manager and round up the staff. We search the whole damn store for nanny and can't find her.
Manager calls cops and when the squad car pulls up nanny pops out of nowhere and says she was there all along. Bull shit. The cops knew she was lying and gave her a warning, but nothing else happened. After that, if adults came into the store with kids, they left with them.
We had our most muscular, menacing stock guys follow people around the store and if their kid took so much as a step away from the cart, Mr. Mean Butch Stock Dude would ever-so-politely warn mommy/daddy dearest to keep their hell spawn under control.
If mommy/daddy let their kid take off again they (with hell-spawn in tow) were escorted to the door and told they needed to find a babysitter if they wanted to shop here. If a kid walked in the door alone, cause Drunky-Pants Parents dropped them off to go to the bar, we'd walk them right back out the exit and over to the bar.
Really cut down on the losses. What an un-attended child doesn't steal, they break.
