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.
Not me, but I read this post on a Confessions site: "I work at Starbucks. When a customer is rude to me, I give them decaf. "
It’s called Blue-Coding since the button for Decaf is blue on the espresso machine. Or at least it was when I worked there about a decade ago. I knew people who did that, but I never would. I was always doing opening shift and the ‘rude’ people had to be on the road around 5AM to get to work. Of course they were grumpy.
