Hey, you may laugh but when my son was young he wanted to work at Wal-Mart, most likely, because my mother, his grandmother, did. Kids always want to follow the career choice of someone they respect. It's not, so much, the actual job but the person doing it. I can imagine that she either knew someone or encountered someone that was a waitress that she admired and this had something to do with her decision.
