I'm suspecting from the first photo that some mom or dad intended to buy their little rug rat the Lego set and the kid started screaming in the store. Then mom/dad is so sick of the screaming they rushed over to the liquor section, grabbed a bottle and plopped the Legos into the empty spot. No toys for junior this trip, he won't shut up. Then good old mom slash dad hauled the kid out to the car, whipped his butt and drove directly home to drown his slash her misery in a pint. I used to have a friend whose only job at Walmart was to replace the stuff on the proper shelves that customers decided they didn't want and just dumped wherever in the store they were at the moment.
My youngest daughter is bad at doing that, and I've tried to teach her better, but when she gets buyer's remorse prior to checkout she doesn't care where she dumps out her grocery cart.
But then my friend wouldn't have a job if it weren't for shoppers like her.
