I got fired from a job via voicemail. They smiled and waved to me as I left for the day and then immediately called me at home (this is prior to cell phones) and left me a message telling me not to come in the next day. Oh, I still came in the next day and made them fire me to my face and to get the reason....which was that someone claimed to have seen me studying during work hours. I know, how will I live with myself? No warning, no "did you do this?" (I mean, I did) just a VM firing me. 10 years later I'm a successful lawyer. Guess all that studying worked out for me in the end and the minimum-wage job in customer service did not.
