I’ve worked at a Walmart unloading trucks, and this stuff happens all the time. When you’ve got 4 people in charge of unloading 4000+ pieces of truck, managers barking at you, stuff gets flung. You think an iPad is bad, I’ve seen big-screen TVs flung. Even if you get lucky and the employees don’t throw your stuff, it will fall in transit—no matter what chain of store, nearly all trucks are badly packed and will have stuff slipping and sliding, in all sorts of weather conditions. I’ve pulled Uncle Ben’s rice off a truck that was so hot it was already cooking in the bag. And while I had the presence of mind to put it aside, there are a ton of employees who won’t notice, or won’t care. It’s honestly pretty shocking. But as this article says, most of the time the product survives just fine. The thing that concerns me is the huge carts of cold stuff that get taken out and left for an hour while being stocked, and the fact that a lot of people don’t rotate any food products as they stock them either. (Canned goods are usually fine, but in dairy and produce you definitely want it rotated.) So take a look around at any local grocery store while people are stocking and double check that they’re not letting your cold stuff warm up and possibly become dangerous. If they are, you might want to say something to them/a manager or find another store.
