I used to work at a National Office Supply store chain. A Depot of sorts. I had been having some major pain in my testes so I called out one day to go see my doctor about it. After doing an exam she determined that it could be cancerous and I needed to be examined by a specialist the following day. Needless to say it was the scariest moment of my life. I called my interim store manager and told her I needed the next day off as well. I was the head of the tech department but when I explained my problem she seemed bothered but told me to “do what you need to do” The day after the second exam I went back to work and the first thing she says to me is how tired she was that morning. I said I was also tired (since I couldn't sleep the night before) but together we could knock this day out. She then got this shitty look on her face and said she didn't see how I could be tired since I just had a two day vacation. I slowly took off my shitty earpiece and radio dropped them on the floor said I quit and walked out. Now I have a way better job at a company that appreciates me and she still works there but has been demoted. I know because I exclusively drive across town to buy my ink from there.
TLDR- Boss was shitty about my cancer scare so I quit on the spot and walked out.
