I have 2 examples.
Ill share one; my stepdad was always a huge piece of shit. He still is, actually. He’d trick us into eating tomatoes. Me at 12 could eat them, whatever. My 5 year old brother was forced to eat them, and got grounded if he didn’t. He would actually force us to eat foods we didn’t like and would literally backhand us across the face for “disrespecting” that we had food on the table.
I worked at a sub shop that had the hottest of the sauces. I told a similar version of this story to my boss, and got my hands on an illegally 'hot" sauce. I poured the whole bottle into a store-bought salsa i knew he’d eat.
I love how you got back at him. Firstly, chance of being discovered is close to zero. And since he’s already into hot sauce, he’d never admit that this one’s too much for him. So either he eats it all up and you get to revel in seeing his red face, or he throws it away and you got one over on him for preaching about food waste. Nice.
He ate it about a year later. It was after I moved out of the house. My mom called me freaking out. He apparently started violently throwing up, his face got very swollen, and had to miss a day or so of work. Mission accomplished.
