What places can a 14 year old apply for in Mesa, Arizona?

A daughter of a friend of ours got a job at Arby's when she was 14. We also got yogurt at a place in Tempe (can't remember the name of it) and the cashier looked so young my husband asked her if she was legal to work. She laughed and said she was 14. Might have been Mojo Yogurt.
