Susan Bushnell was in a hurry when a man, clipboard in hand, approached her outside a Walmart Supercenter in Vista, California, one afternoon last September.
The man asked Bushnell to sign a petition as she wrangled her fussing 5-year-old daughter into a shopping cart. He said the petition would help to raise wages for fast-food workers in California.
"Oh, that's a good cause," Bushnell remembers thinking, having once worked in retail. Bushnell paused her rush into the San Diego County store to jot down her signature.
