Lol, Ross.
I used to cook for my department's Christmas party every year for almost 2 decades.
When it got to be upwards of 150 people attending, my old supervisor and another co-worker, who were foodies, decided to help out and cook a few dishes.
I mentioned to them that they must be super clean before and during cooking, and even in delivering the food safely. I explained some of the Servsafe stuff to them.
I said that all it takes is one person to get sick at an event you catered, and you will be admonished forever.
When they brought in their dishes that year, my supervisor said that he had that in mind, so he scrubbed his entire kitchen with bleach before cooking, and kept cleaning all the while.
I never said anything to him, but his honey glazed ham kind of had a floral note of chlorine, lol. But it was clean!
The other guy just had a dumb look on his face and said his wife did most of their job, so I figured we were good to go.
No one ever got sick at any of my parties, and the people who liked ham also got a teeth whitening to boot.
