I was fired from my job at a convenience store because I had to miss a shift due to back spasms. I went to the doctor because the manager told me I needed a note (not to mention the agony I was in).
Turns out there is a deviation in the lumbar spine.
When I hobbled in to bring in my note, the manager (who had to take my shift) fired me. She didn't even have a chance to hear that my problem was legit (not a hangover).
I think it was more because she was pissed that she had to work 5 extra hours. I probably would've had to quit anyways. Whatever.
