Once I went to my local grocery store to buy bread, and found several of the packages of bread had dead bugs in them. I hadn't noticed til I'd bought mine and gotten outside. When I did notice, I went right back in and asked to trade it in for another. I saw that the entire line of that company's product was full of these dead bugs, so I reported it to the store manager and asked him to remove the other ones, so others didn't buy them. He said, "No - but I'll take care of it." I left. Went back the next day. Bugs still in the bread. I complained and complained and eventually talked to the chain manager, but it took a lot of effort just to get ANYBODY to care.
Another time, when I was a kid, I worked at a movie theatre, and the pump broke that moved clean water into the soda fountain. The fountain started to dispense metal shavings into the drinks; the Sprite was dark and grey. It was a Friday (big-business day). And our boss said: "Serve the colas and the dark drinks, but don't serve the Sprite." (Thankfully I wasn't posted at the fountain because I would have had a moral dilemma being the guy to sell those.)
It shocks me the things that are done to people in food service that go unreported. And by contrast, the little things that become a big deal.
I still feel kind of stupid for throwing out my spinach sandwich the day I heard about all this vegetable business. That poor sandwich didn't deserve its fate. =)
