Primark Retail assistent interview questions

It was straightforward and good interview, it was basic questions about like why do you choose primark and what is good customer service. Overall good interview and they offered me a job and got call within few days and for a student the pay is decent

One on one with the team manager of the department which i was about to get hired. He asked me situasional question like "How would you deal with an angry customer?" or "How do you cooperate in team when you have a bad day"
