After Harper complains that she and Alex never spend time together anymore, Alex decides to tell her parents to hire Harper. She somehow convinces her parents to actually hire her, but it turns out that Harper is a complete klutz and has never worked a real day in her life. After Harper causes complete destruction for an hour, Alex's parents tell her to either make Harper improve immediately or they will fire her. Alex uses "The Serving Wench Spell" to help Harper overcome her skills of an oaf. However, her plan backfires when Harper becomes a strict workaholic, leading Alex to fire her best friend. Meanwhile, Justin starts a tutoring business that makes Frankie feel mad. Frankie tries to get back at Justin by having a bunch of kids try to beat him up. In order to get back at Frankie, Justin gets his dumb, yet strong, students to scare and beat up Frankie and his friends in the ice cream parlor. Harper has been working for only a few hours but suddenly becomes Employee of the Month. Alex then runs into the scene, where Harper is making everyone who wants to use the restroom order something. Alex tries very badly to apologize to Harper, which doesn't exactly work out, so she uses another spell to ruin Harper's great waitressing skills. They make up while covered in frozen yogurt.
