I won't eat homemade if I haven't seen your kitchen. There are some dirty bastards out there. I watched one mum and child make a treat to take to the school, it included popcorn. Child sneezed, a disgusting length of thick snot shot out of her nose, her head went forward and when she righted herself there was popcorn attached to the string of snot. A laugh went up, nothing was thrown away, treats went to school, and I decided I was never eating anything there was a chance a child had helped with!
I knew someone else who's cat wandered around the counters while she was cooking, she'd just give it a pat and carry on...
Baker at a place I worked. Spent as much time with his hands down his trousers as he did with them in the dough...
Another woman, really worried about her appearance and her daughters. Would get very upset if they got the tiniest bit of dirt on them. Visited her house. Her kitchen looked like something out of Hoarders...
Worked as a barmaid in a bar/restaurant. Went in on my own time to clean the bar to my standards. Never ate from the kitchen.
In my own kitchen, for my own family, I use a clean spoon every time I taste what I'm cooking.
