I've never liked that show but you've given me a choice so I'm going to go with fry cook. Think of the fun you could have smashing up burgers!
If you lived in Bikini Bottom with Spongebob and pals, would you rather be a fry cook like spongebob, or the cashier like squidward?
I would have liked being the cashier better but it might make working in the back fun if spongebob was there! Lol!
