I don't get what she's saying. He shouldn't whine about a job at pizza hut because some poor folks are out there working at grocery stores? We're supposed to feel sorry for her because she's somehow inept enough to get injured stacking shelves? Balls. A trained monkey could do her job.
Bighead, if you're not willing to actually find a job you'd like better, then you should take a temporary job you know will be harsher than fuck. Take a few weeks off and sign on for some real man's work, and after that making pizzas will suddenly feel like you're getting paid for slacking off and relaxing.
