Midnight Cookies interview questions

The shop is owned my a step father and a step son. The son seems to be the one who runs the business and claims to be "self taught" and the father is the businessman who's probably funding the whole operation. The father scheduled an interview with me and asked me to call him an hour before the interview to confirm that we're still interviewing. I called an hour ahead and he canceled and reschedule for the next day. I met both the owners who explained how they had several people work for them that claimed they knew what they were doing and they overpaid them and they quit or got fired. The said I was perfect for the job and could even run their Tamarac store possibly. They said I can "grow with the business". They only wanted to pay $10.50 at most. Overall waste of time. Perfect job for someone in highschool or that has no job experience.
