A gas station worker knew the note he left for the manager after his overnight shift was going to get him fired, but he wrote it anyway.

When Joe Blumm's shift at a West Michigan BP station ended Thursday morning, his boss never showed up to take over for him. After waiting more than an hour, he locked up and went home, leaving this note on the door (along with a preemptive "help wanted" sign).

"Fire me if you must," he wrote.

She did, on Friday. But not before someone saw the note and posted it to Reddit, causing it to spread across the internet over the weekend.

"I know I struck a chord with a lot of disgruntled low paid employees who get the short end of the stick," Blumm told Fox 17.

He hopes being slightly internet-famous for quitting his job will help him find a better one.

As for the manager, she admitted she was late Thursday morning, but also claimed Blumm never called her.

"I had it," Blumm said. "I had enough of that unprofessional atmosphere, having to deal with that tardiness and have it come down on me."
