Express Hourly Associate/Co Managers interview questions

I was notified by email that they received my application. Later the manager called me to schedule a time for the interview. The interview took place at the location I applied to. It was a group interview and very relaxed. The manager who called me was the same person who interviewed me. They asked 1. Why Express? 2. Is the customer always right?/How would you deal with an angry customer? 3. Sell me something.
