Mine is a pretty tame example: I never minded the smell of garlic was fine around it… but I took a job for DHL and they had these large tubs of garlic for horses that had to go out to people. There were about 10 of them coming down the belt.
Now I can’t stand it. I’m just reminded of how strong that smell was I was actually gagging. The tubs were heavy, the handles were feedble. Some of the tubs were damaged so I got a bit on me.
I stunk of it for the rest of the shift. It wasn’t even a normal garlic smell it was just so powerful and nauseating.
I once bought a box of cracker jack from a gas station, and I am so glad I looked at what was in my hand when I pulled a handful of what I expected to be delicious caramel popcorn and peanuts was actually a handful of disgusting maggots/mealworms (IDK what exactly; I just know it was wormy bugs and not cracker jack).
Now I can’t really have caramel popcorn without wanting to vomit.
