The real question here is where hasn't Durden worked? His Juvie Hall appointed parole officer sets him up with job after job, only to watch him quit or get fired before a week passes. He's worked fast food, retail, office jobs, you name it, all of which end quickly and disastrously.
There is a mile long list of places he can't go in to, most of which stem from his less than PC methods of quitting.
