Wow, you can never tell with people. Go to someone’s house, and maybe they’re secret toilet-brush-in-dishwasher people. And there you are, innocently using their dishes.
Imagine going to someone's house for the first time without bringing your own poop knife. I thought we all learned from that hilarious story that some houses don't even have a poop knife 😆
Sometimes it's great having life threatening allergies - my whole life I've never trusted food that anyone else has made, I have perfected the art of the polite rejection.
I see things like kitchen sink spaghetti, dishwasher fish, and now dishwasher toilet brush, and I look back at how I've coincidentally dodged all those bullets.
(Growing up, in my house "kitchen sink spaghetti" was sometimes also called "crisper drawer pasta", it was all the wilted, sad vegetables that had been neglected in the fridge. Chopped, roasted, pureed, and served on pasta.... No actual sink involved, we just called it kitchen sink spaghetti because it contained "everything except for the kitchen sink"...so learning that some people genuinely use the bare sink to drain pasta - and not just for click bait and views was disgusting eye opening)
