The last job I quit our manager and his manager both got fired for doing some bullshit so I ended up being the defacto manager of our department handling the minor day to day customer issues while we were basically otherwise unsupervised. After like 4-5 months they transferred another manager to us from a separate location who immediately started gunning for me. He tried writing me up 3 times in a matter of like two weeks over little bullshit things. None of which stuck because it had to go through HR and when I explained my reasoning for doing those things they were like "wtf, no" and dropped it. The weekend after the third one I was talking to one of my brother's friends who's dad ran a shop about it and he called his dad and got me hired there the next monday (which was really cool of him because I didn't think we were that good of friends). Never went back to the other job or even told them I was quitting.
