The Book Stargirl: What does Stargirl say is her occupation of Choice?

Stargirl wants to be a silver-lunch-truck driver.

I told her I wanted to be a TV director. She said she wanted to be a silver-lunch-truck driver.
“Huh?” I said.
“You know,” she said, “people work all morning and then it’s twelve o’clock. The secretaries in the offices walk out the door, the construction workers put down their hard hats and hammers, and everybody’s hungry, and they look up and there I am! No matter where they are, no matter where they work, I’m there. I have a whole fleet of silver lunch trucks. They go everywhere. ‘Let Lunch Come to You!’ That’s my slogan. Just seeing my silver lunch truck makes them happy.” She described how she would roll up the side panels and everyone would practically faint at the cloud of wonderful smells. Hot food, cold food, Chinese, Italian, you name it. Even a salad bar. “They can’t believe how much food I fit into my truck. No matter where you are-out in the desert, the mountains, even down in the mines-if you want my silver lunch service, I get it to you. I find a way.”
