What are your culinary pet peeves?

Mine is when people boil whole onions for soup broth or a pot of beans, then throw the perfectly stewed onions in the trash. Makes me cringe every time.

Not only is it a waste of food, stewed onions are DELICIOUS 😢

Another one is when people fry fish without deboning it. That's absolutely criminal.

Edit: Stop and think before being rude in the comments. People are allowed to dislike something that you like, and vice versa. They're called "pet peeves" for reason. The generalization and misinformation is also becoming very annoying. "Asians don't debone their fish" says who? Half of my family is from Java, and I was taught from childhood how to deboned different kinds of fish. There are also multiple Japanese fishermen on YouTube, like Masaru and Chef Dai, who teaches how to debone fish. Fish bones are a choking risk to young children and elderly people who don't have strong teeth.
