I was fired after having my appendix taken out. The doctor told me that I couldn't drive a car for a week and my "boss" who I actually hired (he was immediately promoted by a corporate manager trying to take over the marketing section in the area) demanded that I meet with him. When I told him I couldn't because I had just got surgery and couldn't drive he fired me.
Oh and he gave a bad reference for a job. Even the asshat corporate manager was pissed off at him because of that and apologized to me.
