Back in 1988, I worked at a grocery store in Richmond, VA. We had a section of bulk snacks, e.g. trail mix, chocolate covered pretzels, etc. While I was sweeping the aisles, I watched an unattended child “grazing” from the bins and then he spit something he didn’t like back into the bin! I immediately notified my manager, but the only thing he did was throw out the whole bin, which was about $30 worth of product. I even pointed out the kid, who was back with his mother, but the manager wouldn’t confront her about it even though I had personally witnessed it. This is why I will NEVER buy anything from a bulk bin.
