I had close family members that worked in the Hershey Chocolate factory. They couldn’t stand Hershey’s Chocolate.
The smell inside the factory was sickening to me.
I remember that the whole town smelled like chocolate. And the at tree lights were candy kisses.
When I was a boy there were a bunch of canneries of tomato products in the town where I lived. I’d rather live 24/7 in a Hershey’s factory than ever again smell tomatoes being processed at scale. It’s quite unpleasant
When I was a teenager I did some construction laborer work at a plant that used my dad’s company routinely. Every time I had to leave my clothes in the garage. It had one of the most intense smells you can imagine.
Wright’s Liquid Smoke. The actual plant they distilled the smoke into liquid. Took two shower’s each night but it stayed in your sinus cavities.
