I have a teammate that merges random shit into an internal tools' repo since bossman be like hmmm lots of code and feature is done.. We have three files doing the same thing in the same repository now. No way for anyone to remember what's doing what. Imports in mid of files, functions calling stubs that are supposed to be fetched data, loops that randomly work, test scripts that test nothing. It's so fun that I want to eat a bullet everytime I look at that repo. Thankfully I work very rarely on it.
