One time I was working as a customer advocate in a hosting company and I had one supervisor that never wanted to concede and refund the clients. It wasn’t an issue with other supervisors, I was following policies and he was kind of an asshole.
At one point I told him he was wrong and he replied with the French expression “you will not live on love and water alone”, meaning do what I say or you will be fired and won’t have money to live.
Well, as this happened before lunch break, I went to lunch, wrote my resignation letter and sent it via email. When I got back at the office he was incredulous and asked if I was joking. Nope.
I didn’t have the monetary meams to quit and I had to go back to my previous job, that I also didn’t like, but at least my old supervisor was not such an asshole.
