I was working on a project a while back making a language system, we obviously wanted to know what language the user had set so I looked to adding it to the database.
I've seen messy code and I'm not a gold standard but fml..
I ask the other dev who wrote the code and we end up spending a while getting it sorted. I had never seen the database before... 100+ fields on the main table...

I quit not long after. Hated that job and I have many things I can rant about from it.
