At the yogurt plant they were supposed to clean up any yogurt they spilled or dripped on the floor at the end of the day. One day I walked in and was told by someone in packing that the crew, when they shut down, that took the garbage to the dumpster left a yogurt trail down the hallway. I checked and yes there was a line of yogurt that had sat out overnight.
This was back when we only had one shift. The next day we didn't start up right way because of some issue the batchers had with making the yogurt (it was greek not batched but whatever) and the offending people, whom had a personal relationship with the plant manager, were sitting around (they called it cleaning) in the break room.
So I rolled over to the plant managers office, being not management, and started to ream him out because his family and close friends left a yogurt trail and were now "cleaning" the break room the next day. His response "What is the risk to the product?"
Hummm... I'm thinking PEST INFESTATION! Why leave yogurt sitting around. He thought I was a food safety firebrand. I agreed. The facts still remained that his family and friends, whom he shouldn't have hired in the first place, didn't give a crap about leaving yogurt just sitting overnight.
I was so happy when he was fired. Now he's a quality manager at a different food manufacturing place. Good luck to them.
